EDIT: While typing this, I figured it must be something DirectAdmin related, and figured out it was the firewall on the DA side.
Hi Guys,
I've been trying to setup PMG as the relay for my DirectAdmin servers and am hitting some strange issues where e-mails are not relayed properly and Exim on DirectAdmin fails with a 'connection refused' when trying to relay e-mails.
Setup as a smarthost in DirectAdmin using this: https://docs.directadmin.com/other-hosting-services/exim/smarthost.html and also using port 26.
I've added my /24 and /48 networks as Trusted Network in 'Mail Proxy --> Networks'.
Additionaly i've added these in 'Mail Proxy --> Whitelist --> IP Network'.

2025-07-07 17:11:35 1uYnID-0000000219v-3kSj H=mx.mydom.com [193.xx.xx.84] Connection refused
I can telnet on both port 25 and 26 from my directadmin server to the PMG, so that seems to be working.
The only issue I keep seeing on the DirectAdmin mail log side is:
I was hoping if anyone has any clue for me where to look at?
