[SOLVED] Relay Domain on Transports

[the.afad]

hi

i just installed pmg and do the basic configuration,
i sucessfully sent/received from my internal mail server to outside and vice versa
the problem is when i add relay domain in Tranports menu for my second internal mail server with different domain of course, second server cannot received incoming mail,
Tracking Center showing rejected log, detail log says 554 5.7.1 <user@domain.com>: Relay access denied;
im see setting relay domain 'use mx' is unchecked, but when i tried to checked it, nothing changes, the setup go back unchecked.
im not sure the problem is because i can't checked it or something else.

Please advise

Have you add your second domain to Relay Domains?
Maybe double check trusted network too.

Thanks @hata_ph for fast reply
You are right, im not add second domain to Relay Domains, I don't think it's necessary because it's already on the Transports
thanks again
