Thanks Stoiko, the settings I make in the UI are properly reflected in both config files:
main.cf: default_transport = smtp:ciphermail2.pie.local:25
pmg.conf: smarthost ciphermail2.pie.local
I can see from the OS logs that whenever I update the SMarthost setting in the UI, postfix is reloaded...
That is a very good question, but I didn't set it up, and that's my problem :)
Right now I am trying to understand the moving parts.
But from a message flow point of view it's these two :
Internet -> Firewall -> Proxmox Mail Gateway -> Ciphermail -> O365/Google/etc
Hi there, I recently have been handed over a cluster of Proxmox Mail Gateways, unfortunately without a proper handover, let alone documentation.
And now I am trying to make sense of things, so apologies if some of my questions are obvious to someone experienced.
My system is set up in a way...
