missing log entries for old version of postfix

I have a machine running a very old version of postfix. In trying to troubleshoot a discrepancy between what some reports I was pulling from the postfix logs vs what my upstream relay was saying I was sending I noticed something that looks off to me. [ssm-user@ip-10-104-84-189 ~]$ sudo grep -E

Wietse, That was one of my test cases. I just tried it again; ssm-user@postfix-warming-c:~$ postconf | grep -E "append_at_my|remote_header_rewrite|local_header_rewrite|inet_interfaces" append_at_myorigin = yes inet_interfaces = all local_header_rewrite_clients = remote_header_rewrite_domain =

I've tried just about every combination of these configs from the docs: append_dot_mydomain (default: Postfix ≥ 3.0: no, Postfix < 3.0: yes) With locally submitted mail, append the string ".$mydomain" to addresses that have no ".domain"

mail queued by transport

Is there a way to see the transport that queued mail is using? I just created a new transport and pointed a domain to it. The server also had mail for that domain queued up under the old transport. Is there any way I can find out what transport the mail is using? I didn't see transport in the

I'm back to the experts for some question. I'm trying to help dig some folks out of hole. Is there anyway possible to make a decision on where to send mail based on a friendly from header instead of the envelope from? I just got done building up a multi-instance postfix set up that was supposed

"Best" way to stop postfix from sending any DSN

I'm doing some testing and am trying to figure out a way to set up postfix so that it won't ever send a DSN. In googling around I found one option is to change the bounce service in master.cf to use the discard service. That seems to stop the DSN for a bounce to be sent out, but I get some

Is it possible to rewrite the envelop from address for all mail that's being relayed?

I'm curios if it's possible to set up postfix to rewrite the envelop from address for all email the instance is relaying? I'm doing some research and want to force the envelop from to be a known value that I know will pass spf checks. Thanks in advance. Sean
