We are currently having problems where mail Andrew sends to luv-main gets blocked by localhost. # postconf -d|grep mynet mynetworks = 127.0.0.0/8 10.10.10.0/24 [::1]/128 [2a01:4f8:140:71f5::]/64 [fe80::]/64 Below are the relevant log entries. It seems that ::1 is not being accepted as an exclusion for spam checks, from the above you can see that ::1 is in mynetworks and from the attached main.cf you can see that permit_mynetworks is before other checks. Any ideas as to what the problem might be and why it only seems to affect Andrew's mail? To clarify, what happens is that outbound mail from the list server is sent to localhost and the Postfix instance on localhost is rejecting it.
From the attached master.cf you can see that localhost is excluded from SpamAssassin and ClamAV checks.
