Hello people. I would like to ask something very basic, which I fail to understand well, and I hope you will help me. I think it would be very nice if what I ask you finds application in the technical documentation.

My configuration is as follows I have proxmox and iredmail.
The things I did
- port 25 (no dns record)
* 25 port is open on the firewall
* redirect all requests that arrive at 25 and they go to proxmox gw
- port 587 (smtp - has dns record)
* port 587 is open on the firewall in two directions
* smtp-record is set for all e-mail clients for outgoing connections (the dns record does point directly to iredmail)
- ports 110,143, etc. (client-iredmail communication)
* 110,143 ports are open on the firewall, etc.
* imap-record or pop3-record is set for all e-mail clients for incoming connections (entries point directly to iredmail)
Are these settings is correct or i had a mistake?

It will help many people with less knowledge (like me) if you do a few examples of what is expected to be set up in case we want to use a proxmox to filter only incoming mail and in case we want to we also use it for an output filter. I mean these and these ports is need to point to mail server, these settings are for incoming mail connections and set on client, these is for outgoing. Just a few "use case scenario" will be superb from user point of view.
Thanks in advance and sorry for mine maybe stupid questions
 
I would do the following for inbound scanning:
* forward all traffic arriving on port 25 of your firewall to PMG
* configure PMG to have a transport (or default relay) pointing to your iredmail port 25
* add your domains to PMG

for outbound scanning:
* configure your iredmail to send all mail via PMG port 26 (set this as smart host

PMG is not meant to deal with client traffic (no imap/pop and also no SMTPAUTH on port 587 ) - let those still connect to iredmail directly

I hope this helps!

That's still a while in the future with the current situation :/ - but glad that helped :)
 
Only one clarification about: " all mail via PMG port 26 (set this as smart host)"
How to do that? Just check smarthost on relaying menu?

sorry - did not explain that clearly - for outbound scanning you need to configure pmg's hostname and port 26 _on iredmail_
(iredmail needs to use pmg as smarthost)
