Hi everyone,
I was trying to use pmg as relay host for some mail servers and I was able to make it work without authenticatoin just putting the pubblic ip address of the mail server in mail proxy settings - network session of the GUI.
I was wondering how could I set up the pmg to accept relay from a mail server with authentication regardless the pubblic ip. Do you know any way to do that?

Thank you in advance for your help!

PS: PMG is great! I love it!
 
PMG uses postfix as its MTA and you can configure postfix via the service configuration templating system - see https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#_service_configuration_templates.

You could add another listener, which only accepts mail on authenticated connections - usually this listens on port 587 (mail-submission) and then configure the servers which should send via PMG to log in before sending the mails - there are quite a few howtos for this out there - but I always like the postfix reference documentation as a starting point: http://www.postfix.org/SASL_README.html

I hope this helps!
 
Sorry to Dig up an old thread however is there a way to do this via the interface? I want to avoid the configuration being overwritten by changes in the GUI if created in the CLI.
 
Thanks, yea I did some testing and this cleared it up for me however I cannot get user authentication working to allow relay :(
