I am using postfix as a MTA. I just installed it and it was very easy. Using the documentation I have it using spamassassin as a transport. Everything seems to work ok except that when I look in the /var/log/maillog I have the entries like the following:
Dec 23 14:09:39 pmcserv1 postfix/smtp[27506]: 71DA3B4599: to=<cb2977@yahoo.com>,
relay=mx3.mail.yahoo.com[64.156.215.5], delay=311, status=sent (250 ok dirdel)
To me, that entry tells me that my mail server just relayed mail to some other system; that's not exactly the result I was looking for. I then tried to do it myself from other locations and it bounces back my attempts with the "Relaying not allowed" message but I keep seeing entries like this.
I have tried looking into this and, as a result, have setup .db (access_sender & access recipients) files using postmap but I can't see a change in these log entries. I also have the server using SASL authentication if that applies to these entries.
This is the only anomaly with the entire thing so if anyone could help me understand what this means I would appreciate it very much. I thought of googling it but that kind of entry has too many quirks with it and google doesn't get me anything useful.
If there are any files that I should post, please let me know. Thanks in advance.
