I have a mail gateway that delivers messages to Axigen.
Problem is that those messages fail SFP and are bounced.
Can I whitelist the mail gateway IP and disable all checks for that IP?
If your plan is to do that, then why bother having the gateway? You’d be essentially bypassing its role.
This could be a recent change or something with how the mail server is handling mail. My mail server suddenly decided to stop allowing all of my internal mails from Proxmox servers to be delivered… just because it felt like doing it. I didn’t change a thing or update. As matter of fact, I updated to 6.7 because of the issue.
I’m frankly about to dump this mail server and get a different solution. It causes more headaches for me.
It wouldn’t bypass it’s role as the mail gateway does all the checking (SPF, DKIM and such).
Mail server is isolated from the internet, and should accept everything from the mail gateway, without question.
I turned off all checks on mail server, but I’d be happier if i could tell it to bypass all checks when messages arrive from mail gateway.
