Hello all.
I am looking if I can use the Proxmox Mail Gateway as an outgoing SMTP service.
I have a local network and several servers in different clouds. I have several domains, and I need to send all emails to anyone, but from one relay.

Yes - this should work - just configure your internal services to relay mail to your PMG on the internal port (default is port 26) - and add their ips to
GUI->Configuration->Mail Proxy->Networks

See the reference documentation on the topic:
https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#_filtering_outgoing_emails

I hope this helps!
