I am seeing trigger_server_accept_fifo log entries unfortunately I
cannotassociate the trigger to a specific message. I did notice the numberof
qmgr trigger log entries are 60% the number of message processedlog entries. I
know postfix logs a single line per recipient and that couldaccount for some
but not a 40% difference.
I completely left out one observation. The messages are accepted, theyare
sitting in the incoming queue. There is little or no mail in the deferqueue.
The active queue has a few hundred messages. I am not seeingany significant
number of errors for milter nor ldap queries.
