Axigen behind Email Security Gateway

Support Security
1

Hi,

I’ve been running a Free Mail Server for some time. Now I want to migrate my company’s email (around 55 users) from google workspace to the axigen server I am configuring.

I would like to know if, for security concerns, it would be recommended to put axigen behind a Secure Email Gateway?

I would appreciate it if you could share your experience on this issue.

TIA,

ntsetso.

That should be a standard configuration for any hosted mail server. I use a Proxmox Mail Gateway for my Axigen server, with a SMTP Relay Host using Authentication to send mail (home ISP blocks the port of course). The mail gateway works fine in front of Axigen.

Amodin, how do you have the anti-spam settings configured? I have found that I have to disable SPF filtering because Axigen rejects email received from my mail gateway. Is there some configuration for adding the mail gateway as a trusted server? The safe IP list does not seem to work, i.e., it appears to be referenced after the SPF filter.

Do you not have your mail gateway listed here on port 26?

Amodin, Thank you for response. I do have the gateway connected (outgoing) on port 26. My issue was for the incoming messages as they were getting blocked by the SPF filter (greylisted). In the end, I just turned off greylist filtering as everything is actually coming in via the mailgw, i.e., always from the same IP (which is not in anyone’s SPF).

Glad to hear it was simple. I learned early on that greylist is just another word for ‘pain in the butt’.
