Gmail sends my mail to spam despite perfect SPF/DKIM/DMARC. Postmaster Tools shows 0% spam. Escalation rejected. What now?
Posted by AlexSparkin@reddit | sysadmin | View on Reddit | 95 comments
Hi colleagues! I'm running my own mail server and I'm completely stuck. Hoping someone here has dealt with this before.
The problem: Emails from my domain go to Gmail spam every single time. Other providers (Outlook, Yahoo, Proton, corporate mail etc...) work perfectly.
What I have configured:
- SPF, DKIM (2048-bit), DMARC -- all valid and passing
- DMARC policy: p=quarantine (tried p=reject as well)
- PTR record matches HELO/EHLO
- IP is clean -- not on any blacklist (Spamhaus, Barracuda, etc.)
- Domain is 20+ years old
- Direct SMTP from my own IP (no relay)
What I've done so far:
- Connected domain to Google Postmaster Tools --- shows 0% spam rate, but real emails still go to spam
- Submitted escalation forms -- rejected with "insufficient traffic"
- Checked with Google Check MX -- all technical checks pass
- Verified DKIM via email headers -- shows "pass"
Question for the community: Has anyone successfully recovered from this situation without sending thousands of emails per day? Are there any escalation paths beyond the standard forms? Would switching to a dedicated relay only for Gmail (while keeping direct SMTP for others) help or hurt?
(Mods, please don't remove. No links, just asking for advice. First time posting here.)

One thing that seems to help is to contact everyone you are sending emails to on a gmail address (using an alternate sender, of course) and specifically ask them to whitelist your domain. I used to have a lot of problems sending to gmail, but after a few hundred whitelists, I guess they got the message.
igiveupmakinganame@reddit
how old is the domain?

A couple jobs ago our CEO thought he was a bigshot SEO so he snagged a copy of the emails for everyone the company had ever spoken to, not just customers, and blasted out the most keyword-laden email I've ever seen.
Once we pried ourselves off of all the blacklists and were still getting blocked we figured out that merely saying the name of our company in an email was enough to get it flagged as spam. It's a level of reputational damage that's difficult to test for, and impossible to address.
We had to tell our sales people to take the company name out of their email signatures.
johor@reddit
Many moons ago a marketing genius blasted an All Contacts email to their entire customer database; some 12,000 emails from memory. Their Exchange was hosted on-prem and shared a physical server (no virtualisation) with their DC and primary file server. The DC slowed to a crawl because Exchange blew out the RAM trying to cache the send queue. Since their internet was an old ADSL connection it couldn't handle the output, so it bottlenecked the outgoing mail queue. Finally, after the first few hundred emails left the server they ended up on a number of blocklists. It took me days to unfuck that particular mess.
fubes2000@reddit
Ha, it was always fun sorting through 50k+ mail queues trying to nuke spam and trash, but at least the servers that I worked on were qmail/sendmail/postfix so it was just a pile of files and not whatever nightmare I assume Exchange used/uses.
AlexSparkin@reddit (OP)
I have a strong suspicion that this is partly ‘my story’, because I’ve been sending New Year’s greetings to my close friends and relatives for about 20 years now. And previously, I used to do this simply by adding everyone to the CC field (I always did it that way).
And this nightmare, in my opinion, correlates precisely with that kind of mailing. That is, I moved the server and after a while Christmas and New Year came round, and off we went....
daweinah@reddit
Security Now discussed a similar issue a little while back.
https://www.grc.com/sn/sn-1045-notes.pdf
jsm_consulting@reddit
I work in email deliverability. This is a common Gmail-specific issue with self-hosted servers and it's frustrating because your technical setup is actually correct.
The problem: Gmail weighs sender reputation and engagement signals much more heavily than authentication. Your SPF/DKIM/DMARC passing is necessary but not sufficient. Google Postmaster Tools showing 0% spam rate with "insufficient traffic" is the tell. Gmail needs to see consistent volume and positive engagement (opens, replies, moves from spam to inbox) before it trusts a low-volume sender.
A few things worth checking:
Your sending IP's neighborhood. Even if YOUR IP is clean, if your IP range has a history of spam from other users on that subnet, Gmail penalizes the whole block. Check your /24 range, not just your individual IP.
Body content and formatting. Gmail's content filters are separate from authentication checks. Plain text emails with minimal links tend to land better than HTML-heavy messages from low-reputation senders.
The relay question: using a trusted relay (like Google's own SMTP relay, or a service with established Gmail reputation) specifically for Gmail recipients can work as a bridge while you build direct reputation. It's not ideal long term, but it solves the immediate problem.
If you share your domain, I can run a deeper diagnostic beyond what Google Check MX shows. Sometimes there are subtle issues that standard tools miss. No charge.
AlexSparkin@reddit (OP)
The problem is made even worse by the fact that I don’t send out any newsletters at all. I simply use email for correspondence and for my small business. That works out at about a hundred emails a year. But everything I’ve read in the advice suggests that I should ‘warm up’ my IP by sending a couple of dozen emails a day and building up to hundreds and beyond. All my friends and clients will block me if I start doing that :)
samo_flange@reddit
tough talk time.
I am one of the most ardent self-hoster proponents you will find. However, if you have to sink this much time and effort into being able to send emails successfully, would it be more cost efficient to just host your email with a provider on your custom domain? M365 or Google are not the only kids in town either. Proton or Tuta will happily host your email, give you real privacy options, and are not prohibitively expensive.
Glass_Call982@reddit
This can all be easily resolved by using a smart host for outgoing email. I use barracuda but never have any issue with landing in Gmail inboxes.
flecom@reddit
Proton will not give you privacy
https://protos.com/protonmail-hands-info-to-government-but-says-its-not-google/
samo_flange@reddit
This linked article might not state what you think. Proton will not necessarily give anonymity based on this information. Privacy ≠ Anonymity.
AlexSparkin@reddit (OP)
It’s always nice to meet a colleague :)
That’s exactly what I’m trying to do. I’ve got my own VPS, my own domains and my own mail server.
Or have I misunderstood you, and are you suggesting to use a third-party MX service? By the way, does M365 and/or Proton actually offer MX hosting?
Well... overall, of course, that would solve the problem. But why should I then be swapping one problem for another? And it seems strange to me, all the same, to pay extra for something I can configure myself anyway, just so that emails from my domains arrive in Gmail without a hitch...
MyNameIsHuman1877@reddit
So their suggestion to prove you're not spamming is to spam? 🤦
AlexSparkin@reddit (OP)
It’s paradoxical, but that’s actually how it is :)
What amuses me most is the fact that relays are, in essence, services designed for mass mailings. And that’s exactly what they’re used for. And mail flows through relays like a dream. Whereas with private, standard IP addresses... this is what we end up with.
Public_Fucking_Media@reddit
You need to fix your sending issues before you start warming up the domain anyways...
saltyslugga@reddit
This is a classic low-volume self-hosted sender problem. Gmail's spam filters weight sender reputation heavily, and if you're sending low volume from a single IP with no established history, technical perfection doesn't matter. You pass every authentication check and still get junked because Google doesn't trust you yet.
We hit this exact scenario on a fresh IP during a migration. Two things actually moved the needle: getting real recipients to drag messages out of spam and mark "not spam" (this trains Gmail's filters for your domain), and slowly ramping volume with engaged recipients who actually open and reply.
Switching to a relay for Gmail-bound mail can help if the relay has established reputation, but it's a band-aid. The "insufficient traffic" rejection from Google is them telling you the problem directly. You can also try running your Gmail-bound mail through a reputable outbound relay temporarily while you build up direct sending reputation over time.
Quick sanity check though, run your domain through this tool to make sure there isn't something subtle you're missing in your records. Sometimes a small misconfiguration flies under the radar.
PhotoJim99@reddit
It’s not quite so dire. I have a very low-volume personal domain. I have had SPF on it for years, but recently (as in January) added DKIM and DMARC. I seem to have 100% success in getting emails properly delivered (touch wood). I started by having SPF set to “accept” and eased my way to “reject” after a few weeks of DMARC reports. I did find that one of my domains (that I actually don’t use for email at all) has a few spam emails sent every week with the sender domain showing as mine - all of these are now (correctly) rejected.
AlexSparkin@reddit (OP)
Thanks for the tip!
Basically, that’s pretty much what I’ve come to realise, and I’m sticking to it. I’d ask everyone to ‘tick the boxes’, ‘add’ and ‘reply’.
The only thing that confuses me is this... it’s not entirely clear what Gmail’s reputation is tied to more: the IP or the domain. And how using a relay builds reputation (if it’s the IP’s reputation to a greater extent).
But yes, for now I’ve switched one domain entirely to a relay, for lack of alternatives.
Slight-Blackberry813@reddit
FYI this is why mail relay services like Mimecast etc exist.
saltyslugga@reddit
It's both, but they weigh them differently depending on volume. Low-volume senders get judged mostly on IP reputation because Google doesn't have enough domain-level signal yet. Once you're pushing enough mail that Google can build a profile on the domain itself, domain reputation starts to matter more.
The relay helps because you're borrowing an IP that already has that established trust with Google. Your domain reputation still builds over time through engagement signals (opens, replies, not-spam clicks), which is exactly what you're doing.
fengshui@reddit
I experience something similar to this, but less bad than the OP. I am very low traffic, but my IP has been stable for a decade. There's not much structurally you can do, but it does generally work okay. When I'm sending emails to someone I haven't emailed before, I will send the first message from my Gmail, ccing my personal domain address. That usually is enough to get through the initial screen.
FarmboyJustice@reddit
Have you checked for other blocklists besides by IP?
Spamhaus ZEN is notorious for flagging senders based on vague things that can't be explained.
How are you confirming that email always goes to spam? Have you tried using an inbox delivery test?
How many people have you sent email to and had them report this?
AlexSparkin@reddit (OP)
yep, mxtoolbox (mate, you’ve no idea how thoroughly I’ve checked and configured everything)
All my recipients confirm this. There have been instances where emails didn’t arrive at all. I’ve asked people to resend emails to my address several times and replied until I managed to get them through.
At the moment, my email-sending routine looks like this:
I write an email. Then I send a text message asking the person to check their spam folder (if I have their number). And with every email, I include a detailed request to reply, add me to their important conversations, and add me to their contacts in the Gmail interface. But this only helps for a few weeks. Then everything goes back to how it was before.
If I only have an email address for a contact and, by some misunderstanding, it’s on Gmail (my old university friends, for example), then I can’t get in touch with them at all.
FarmboyJustice@reddit
Well this sucks, it sounds like Google has it in for you.
Each big provider has their own shitty AI-based system now, and no humans ever bother to look into anything. Works great for bulk management of huge environments, but it sucks to be the small guy who gets caught up in the nonsense.
Things I'd try:
Get people to forward your emails to you as attachments so you can review the headers and look for any clues there.
Verify RDNS is actually correct for sure
Change your DMARC policy and see if you see any change in the behavior
Change all the things: Get a new IP address for the server, change your server software, email client, try using a subdomain for email.
Try using a different email service temporarily to the effect. After a while, switch back.
Most likely this is going to be a case of Google just has it in for you, and there's no recourse for that, Google is basically god of the internet, they have an effective monopoly on email, search, and browsers.
irioku@reddit
Forwarding the emails to him would just taint the header. Export it as a .eml and send it.
stackjr@reddit
My dude, that was literally their first point.
jmgib@reddit
They said to forward the emails as attachments. Meaning the original emails would be attached to the new message and thus preserving the original headers.
drashna@reddit
and microsoft, and amazon, and ... etc.
even using properly configured dns, smtp, etc.... I get mail that is never delivered... at all.
Dead internet is real, and email is dead. Except for spam, because that seems to have no issues getting delivered.
Brilliant-Advisor958@reddit
Is this a business or home setup?
5panks@reddit
This has the be the worst widely accepted IP blocklist in the entire world.
johor@reddit
It sounds very much like a low-usage domain issue as others have mentioned. Sounds like you need to "warm up" your sending IP.
cpodable@reddit
Hey mate, have you tried changing the subject of your email? Bit of a wild one but we've had a similar issue last week and the only thing we could do to get the email to go through was change the subject line. Something really stupid but definitely worth a try.
Public_Fucking_Media@reddit
Oooh, I have dealt with this a lot actually... I have several questions!
what are your compliance stats on the new Postmaster?
what are your daily sending volumes, both historically and recently?
what is the content of these emails?
why are you self hosting?
are you absolutely sure you have followed all of googles new requirements for email senders? The fact that you are self hosting makes me think you probably aren't... ( https://support.google.com/a/answer/81126?hl=en#zippy=%2Crequirements-for-all-senders )
AlexSparkin@reddit (OP)
you’ve no idea how thoroughly I’ve checked and configured everything
still no results
Public_Fucking_Media@reddit
2/3. That isn't enough emails. After you fix any other issues start emailing your personal gmail every day back and forth multiple times, marking everything as NOT spam. Ask a few friends (NOT customers) to help do the same. A few dozen emails a day is enough to help fix this.
Well, no, you can't, hence this issue you are adding needless complexity to...
Check them again, especially the PTR and header ones, and implement the bulk sender requirements even if you obviously aren't one.
elatllat@reddit
That's not my experience.
fengshui@reddit
Agreed. I have a domain that's verified in postmaster tools and has been so for over 5 years. All of the reports say "no data to display at this time".
Public_Fucking_Media@reddit
The reports are not the confirmation dashboard (and it's been updated to a v2 in the last year or so)
Public_Fucking_Media@reddit
I've used it on every kind of domain from super old with thousands of sends per day to brand new weird domain hacked domains with almost no sends at all and it's always worked - you have to send to gmail addresses a few times that's about all it takes?
Alexis_Evo@reddit
This is a big thing people don't get, Gmail's spam AI doesn't care much about a Spamhaus listing, it's just one of millions of datapoints it is looking at. You're much more likely to get filtered over the contents of the email.
Are you verifying every subscriber's email address? Do you include one-click unsubscribe options with every email? Are you limiting non-transactional emails (marketing)? Are you avoiding clickbait-y subjects and headers?
Fun fact, in the US any commercial email must include a physical address in the footer under the CAN-SPAM act. Most people won't even notice or care about this, but the Gmail AI will.
It is ultimately almost always cheaper/easier to just pay a third party SMTP platform. Because the providers do their own filtering, they are inherently trusted more by the Gmail AI.
FarmboyJustice@reddit
Most of this is not relevant to the original post. This isn't bulk email.
robreddity@reddit
Gmail is treating OP as though he has the rep of a 15 year bulk emailer. So it might be called for to adapt similar strategies.
Public_Fucking_Media@reddit
For such a low send domain it actually can - you need to over-comply in such cases (and some of the bulk sender requirements/recommendations are just good practice and will become requirements for everyone eventually)
Alexis_Evo@reddit
I didn't see any reference to type of email in the OP, but they do mention in replies that it is personal email, so you are correct. Most businesses I see trying to self-host their email are mixing personal/transactional/bulk on the same server, which is going to be the nightmare I described.
Public_Fucking_Media@reddit
God I hate that I understand every word of this post.
Affectionate-Cat-975@reddit
If you’ve been flagged by some people Gmail will flag it for all its users.
deebeecom@reddit
Did you ever create a Google account using any email address which uses your domain name. Log into that account and see if it has any issue inside it. If Google marks that account as disabled or suspended, then that bit is read by all Google tenants including by Gmail.com. Delete that Google account if not needed. Sorry it’s a thought.
AlexSparkin@reddit (OP)
That’s a good guess. I thought so too. Yes, I’ve used it for Google Ads. Everything works flawlessly, and emails arrive straight into the Inbox of the relevant Gmail address (surprisingly).
I even tried to sort this out through their support, but they sent me to Workspaces, where they charge you to speak to a live support agent. I’m not sure I want to do that, or that this is the way things should be on a free, neutral Internet. :(
deebeecom@reddit
Probably they maintain their own database (well I think I am confident they do) which their own customers refer to and or possibly one of their customer has marked your address as spam or something….
jeffrey_f@reddit
Regardless, if at some point, you or someone with access to your email marked that sender as spam. From that point forward and likely only in your account, that sender will be spam and treated as such.
You can mark it as not spam, but it may take a few times to stop treating as spam

mb194dc@reddit
What kind of IP are you sending from ?
Use your domain with a 3rd party SMTP service.
AlexSparkin@reddit (OP)
dedicated IP, my VPN, clean subnet. reverse DNS etc...
The Autonomous System contains IP addresses that have previously appeared on spam lists, but 99% of VPS providers’ AS-es are generally affected by this. And this should not have any impact.
Psymia@reddit
Is this from an IP range that is assigned to an ISP as enduser space?
I've had issues with microsoft a few years ago where i've been blocked because the range where i operate my server in has been classified as such an "end user range". The server is actually in a datacenter and the range is not for end-users bit servers. Had to provide some info and the range got reclassified.
Not sure this helps you, but my takeaway from that was that running a mailserver in the datacenter works, but may not work as well when running from home (even with a static IP).
jrandom_42@reddit
Try sending via Amazon SES for a bit, just as a test. It's basically free at your sending volumes and it will show up any IP related issues with your self-hosted design. If filtering behavior is unchanged when sending via SES, then you know it's not IP related.
bbqwatermelon@reddit
Yep or a security gateway because their IP addresses are always trusted.

PTR was the first thing I set up when configuring the server :)

AlexSparkin@reddit (OP)
I strongly suspect that the AI they use for filtering might include parameters we’re not even aware of. And of course, this all includes statistics on ‘conventionality’ (let’s call it that).
Yes, I use ClawsMail, which isn’t the most popular (but is the best, imho). But what has it come to if we have to change our email client just to adapt to the centralised monopoly’s filters, based on our flimsy guesses about how the weights are distributed in their tensor tenets?
I hope the hole isn’t quite that deep yet :)

hotfistdotcom@reddit
What do you do with this mailserver? Google has their own rep and if every person you are sending something to flags it as spam, they are going to start sticking it in spam.
AlexSparkin@reddit (OP)
I use it for personal correspondence and for communicating with clients. That’s all. It’s all very straightforward. No mass mailings.
hotfistdotcom@reddit
Your best bet then is probably to hire someone specializing in gmail - many MSPs do gsuite stuff for small clients, and see if they can help you get this sorted out with expertise. Just from looking over the comments here there is a lot on the gsuite side that is difficult to account for the way you are looking at it, and it might be best to dig into it with someone who can help you get a really good handle on the system from an administrative perspective, and who can work hands on with you.

steavor@reddit
Simple answer (but not what you want to hear) - Google DGAF about you. They don't need micro MTAs sending 2 mails a day to them, and they most certainly don't need to bother an actual human with your issue.
Whatever the "actual issue", nobody there is going to care about it, you're not going to find out what it is, and more likely than not it's nothing more and nothing less than the tiny volume of mail itself that makes you seem "suspicious" in their eyes. You've already seen it in multiple replies to your post here on Reddit, people are outright wondering why you spend your own time building expertise in SMTP RFCs if that's not even the point of your small business? The crowd here acts even more incredulous if someone dares to post that they're a small mom and pop shop, but running MS Exchange on-prem. "Are you stark-raving mad? O365!!!!"
"Just pay a few dollars to make email another persons problem" is Googles answer to your particular issue, most likely. Centralisation of the Internet is where it's headed everywhere, unfortunately.
kerubi@reddit
I suppose there is nothing noteworthy in your domain’s RUA/RUF reports from Google?
Broekan@reddit
When you say that the SPF and DKIM are passing, is that in a testing tool or from the email authentication stats in Gmail?
AlexSparkin@reddit (OP)
both
Apachez@reddit
Gmail seems to have entered full retard mode lately where there are no humans who seems to be able to assist from Gmail support.
Since late february this year there are also issues with mailforwarding to gmail accounts where the emails are accepted without error but then not even shows up in the spam folder of the recepient - they are just gone:
https://www.egensajt.se/nyheter-och-meddelanden/175/Viktig-information-om-vidarebefordran-till-Gmail.html
(Use Google Translate if you dont know swedish).
Your case is technically different since you originate with your own domain as I understand it but it can perhaps still be related to the above fuckery of mailforwards who just disapears within the Google datacenters?
Or perhaps they are just sinkholed to some NSA collector? ;-)

No-Rock-1875@reddit
Sounds like Gmail is flagging you on reputation rather than the auth checks you’ve already nailed. Start by cleaning your list even a few dead or role‑addressed emails can tank the “spam‑like” rate in Gmail’s eyes, so run a quick validation and purge hard bounces. Send a few low‑volume, high‑engagement messages (think personal or transactional) from the same IP and monitor the “Inbox” vs “Spam” metric in Postmaster Tools; a steady warm‑up usually nudges the reputation back up. Also double‑check the content avoid excessive images, all‑caps subject lines, and generic “unsubscribe” wording that Gmail treats as spammy. If the problem persists, routing Gmail traffic through a reputable relay (SendGrid, Mailgun, etc.) can give you a better‑known IP reputation while you keep the direct route for other providers.
AlexSparkin@reddit (OP)
> low‑volume, high‑engagement messages
In fact, all my correspondence is like this
> metric in Postmaster Tools
I have 0% spam according to these metrics (one year of monitoring).
DMARK reports also show 100% delivery. No complaints whatsoever.
> check the content
I've even stopped adding smiles :]
> relay
Yes, yes, that’s exactly what I’m considering as a last resort. But that’s not why I moved everything to my own server back in the day. I want everything to work without being controlled by the big vendors. Just as it has been for decades since the Internet first appeared. Sorry for the sentimentality :)
I tried Relay on one of the domains where clients write and deliverability is essential. Yes, mail goes through it perfectly. It just doesn’t arrive in the Inbox but in Promotions. And after I switched back to my own IP, the mail that used to end up in Spam stopped being delivered at ll.
No-Rock-1875@reddit
Yeah, Gmail will still downgrade you if the IP is “cold” or you’ve mixed bulk and transactional traffic auth alone isn’t enough, you need a proper warm‑up and a consistent sending pattern. Adding a List‑Unsubscribe header and keeping bulk on a separate IP usually helps push you out of Promotions/Spam.
computerguy0-0@reddit
You just need a bit more email volume. Find an email warm up service. Several are free to get started.
viciarg@reddit
Check mxtoolbox.com. They also have a free service where they send you DMARC reports for passed or rejected mails.
DueSignificance2628@reddit
Does it pass all the checks according to Gmail? In Gmail, open up the email in the spam folder and show the headers. It'll show if Gmail itself thinks it passed DKIM and SPF.
It could be that you have a cold IP though. Is your IP address in a block from a datacenter. or a home internet IP?
ThomasTrain87@reddit
Following as I have the exact same issue.
AlexSparkin@reddit (OP)
Yeah, I’ve seen loads of examples like that. I keep coming across complaints of this sort, and it all basically boils down to the advice to sign up for a Google Workspace account (the paid) so you can contact support. Then maybe Google will take pity and enable a separate filter for my IP (though there’s no guarantee).
It’s a brick wall :(
reilogix@reddit
Which company/service hosts the sending email server? In my particular case, I learned via learndmarc . com that the [Google Workspace] customer had 2 domains in their Workspace account and one was a User Alias Domain and I am still untangling that one...
