Advice for getting off of ProofPoint's Dynamic Reputation blacklist?

Posted by eclipseofthebutt@reddit | sysadmin | View on Reddit | 3 comments

We got blacklisted a while back by ProofPoint due to our ISP deleting the PTR record for the IP we send mail from, and I have not been able to get any response from their web form.

We remedied the PTR record issue and got an apology from our ISP, but by the time we did it was too late.

Has anyone had any luck getting off of their list and if so what did you do?
