Hello,
Unfortunately I can't get any further.
I have two mail servers running on the LAN
External communication works without problems (external to internal and back)
Mails from Domain1 to Domain 2
and as well
domain 2 to domain 1
The error comes:
Result: delayed, Status: 5.5.4 Cannot find hostname "Domain1.com"
I would have expected mail.Domain1.com here.
The servers can resolve the names among themselves without any problems.
There must be something in the DNS, but unfortunately I can't get any further.
can someone help me with this?
What other information can I give you about this?
ps. when the 2nd server was still hosted in the WAN today, this problem did not exist.
