Should be a short one, I was just forwarded an email chain between a web developer, and one of the owners of a company which we recently started providing IT services for.

A web developer designed a new website for our client. The web developer decided that since their old email address, info@example.com was receiving so much spam from being listed on their website, that they abandon it and use a new email address instead (enquiries@example.com).

In the meantime, we've just migrated their mailboxes to Microsoft 365 and decided that we should keep the info@ mailbox, and redirect it to the new enquiries@ mailbox, since the better spam filtering from M365 will filter out the spam.

1, The web developer emailed to say that we didn't need to migrate their emails as the old website didn't have a certificate and was using HTTP, but since the new website will have a SSL certificate and will use HTTPS, that it's secure and they shouldn't get anymore spam.

1. Our client responded to say that since we migrated them to M365, they've seen a 95% reduction in spam, therefore they're happy to be MIGRATED BACK to the old email server since the spam issue has been resolved.

I'm shaking my head. We usually have these kind of strange issues with web developers. We've had issues in the past where web developers change our clients DNS nameservers because they created a new website, and then tell our client that that's the only way for the new website to work. Completely breaking other services. We do try to keep control of domains away from our clients but they don't always listen.
