This mismatch is a very common trait of zombies and spamming machines. My SMTP server takes RFC 2821 very, maybe even too seriously, and barks every time a message is received, and that is after telling it to actually accept the connection: before that it would simply drop it (violating said RFC 2821, but it works wonders against spam) and bark as well. Does this have an easy fix?
Hints are welcome. The machine name is configured as hades.cslab.ericsson.net
and the IP address in DNS is 18.104.22.168. It also has a few other IP
addresses e.g ns.cslab.ericsson.se: 22.214.171.124. Postfix is configured
to use hades.cslab.ericsson.net.
But it seems outgoing sockets nevertheless appears to come from
I will try to change the IP address order in /etc/rc.conf to see if
it can affect which address is perceived to be the real address...
