Axigen behind Email Security Gateway

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.
