# grep -v ^# /etc/hosts 127.0.0.1 localhost ::1 localhost I guess I only have two things left to try now. 1) change the transport SMTP destination IP address (I have another server I can use) 2) diff the whole /etc/postfix dir between the postfix server that's "failing" and the other one that seems to be forwarding fine. The only difference between the two is the software version. The problematic one has postfix-3.1.6, the other one has 3.4.5. I'm more keen on thinking that it's a config or network issue than some sort of a bug or "feature". Thanks, Vieri
