Does this still present a significant threat these days, or is it okay to permit partial messages?

In this case, I want to allow emails by all other users, but reject any attempt for user "local_usr" to send any email from this server. But so far, I can't make the below configurations/commands work. This postfix server relays to another close-by relayserver which forwards the msg to an external server. If possible, I would prefer to reject on the local email server before it hits the relay. If at all possible, I would also like an error condition/status in the smtp client, but thats not a huge problem. I have provided as much diagnostic config and log data that I can imagine, but I am more than happy to provide more, can anyone see what I am missing?

I recently opened port 587 in master.cf and now i'm asking myself if it is ok to close port 25 completely? AFAIK every mail server should accept incoming mails to postmaster&lt; at &gt;myserver, but when i close port 25 this is not the case anymore, isn't it? and another question regarding port 25; when my postfix server generates a bounce message (which happens when sending a mail to non existend address) and sends it back to the originally envelope sender, he uses "From: MAILER-DAEMON&lt; at &gt;myserver.tld" as sender of the bounce message. Does MAILER-DAEMON&lt; at &gt;myserver.tld has to be an existend mail account? We recently had problems that on MX site of our email addresses (hosted by a company) they rejected some of the bounce mails generated by my server.

To make postscreen see the changes we have to reload postfix. Yesterday we found postfix was reloaded more than 3000 times. Sure it is not acceptable. What would be the best way to refresh postscreen blacklist (something like kill -HUP) without paying the penalty of losing performance? Would changing cidr type to hash do the trick?

I checked the maillog and I can't tell what's wrong. The email is from another co-worker Liz (liz&lt; at &gt;ourcomapny.com), and there are 3 recipients: Jay, Bob, and Larry. The other two got the email but not Jay. Could someone help me read the maillog and tell me is there something I missed? I don't know how to explain to Jay why the mail is lost.

For example: postcanonical [-r | -s] target&lt; at &gt;domain.com using recipient_canonical_maps = hash:/etc/postfix/maps/canonical-maps mapping &lt; at &gt;domain.com to &lt; at &gt;domain2.com using recipient_bcc_maps = hash:/etc/postfix/maps/recipient_bcc copying target&lt; at &gt;domain2.com to target1&lt; at &gt;domain2.com, target2&lt; at &gt;domain2.com using transport_maps = hash:/etc/postfix/maps/transport using transport virtual to deliver The above is a very rough draft - but something like this that exposes Postfix's thinking, instead of just trying to send/recieve a test message and reading the logs to see what happens - could be a very powerful tool for correctly configuring various map settings and diagnosing problems. </pre> Daniel L.

In theory, it is possible to use the canonical-sender and sender_bcc_maps functions. In practice, the address on the right of the canonical-sender map and the address on the right of the sender_bcc_maps may not be the same. Is there any solution?
