I see only one inet_interfaces setting, and two differfent myhostname
settings. The Postfix SMTP client detects a mail loop when it
wants to connect to port 25 and:
- Either the server IP address matches the client's inet_interfaces
setting (in this case Postfix does not even attempt to connect).
- Or the server greets the client with the client's myhostname (in
this case the client logs that the server greets with its own hostname).
Which scenario is it?
I suggest setting inet_interfaces explcitly for both Postfix
instances.
