Relay access denied

[maestrotr]

Hi,
I am trying to use PMG as my outbound relay server for an Exchange server and whatever I've done, I still got "Relay access denied" error.
Yes, IP is in the trusted network and yes the domain is in relay domains and transports list.
Am I missing another step? I read all the document step by step with no success.

I have one Ethernet card with one ip

Any recommendations?

is exchange configured to send mails to the internal port of PMG? (default is 26)

check out the getting started guide in the wiki - https://pmg.proxmox.com/wiki/index.php/Getting_started_with_Proxmox_Mail_Gateway

I hope this helps!

Ops, that's the thing I missed. I had to use port 26. Now It's working! Thanks.

By the way, who has this same problem with Microsoft Exchange 2016 or 2019, default send connector does not have an option to change port with the web interface, You have to use Exchange Management Shell. to change the port of the send connector to relay PMG on port 26.
