I finally managed to isolate this. I have no been receiving mails from some mail servers and there's very little being logged. I obviously set some configuration that mucked things up. Here is the entire mail.log from the first minute after midnight:
Apr 17 00:00:09 mail postfix/postscreen[67061]: CONNECT from [94.237.32.243]:46598 to [65.121.55.42]:25 Apr 17 00:00:09 mail postfix/dnsblog[74920]: addr 94.237.32.243 listed by domain hostkarma.junkemailfilter.com as 127.0.0.1 Apr 17 00:00:09 mail postfix/dnsblog[74920]: addr 94.237.32.243 listed by domain hostkarma.junkemailfilter.com as 127.0.1.1 Apr 17 00:00:09 mail postfix/dnsblog[74865]: addr 94.237.32.243 listed by domain score.senderscore.com as 127.0.4.97 Apr 17 00:00:09 mail postfix/dnsblog[74950]: addr 94.237.32.243 listed by domain list.dnswl.org as 127.0.9.2 Apr 17 00:00:10 mail postfix/postscreen[67061]: PASS OLD [94.237.32.243]:46598 Apr 17 00:00:11 mail postfix/smtpd[84666]: connect from wursti.dovecot.fi[94.237.32.243] Apr 17 00:00:37 mail dovecot: imap-login: Login: user=<kreme>, x.x.x.x, PLAIN, TLS Apr 17 00:00:37 mail dovecot: imap-login: Login: user=<kremels>, x.x.x.x, PLAIN, TLS Apr 17 00:00:37 mail dovecot: imap(kreme): Logged out in=34 out=497 Apr 17 00:00:37 mail dovecot: imap(kremels): Logged out in=34 out=497 Apr 17 00:00:39 mail postfix/smtpd[84666]: disconnect from wursti.dovecot.fi[94.237.32.243] ehlo=1 mail=0/1 rcpt=0/1 data=0/1 rset=0/1 quit=1 commands=2/6 As you can see, 94.237.32.243 connected and then after 30 seconds disconnected. It says it sent an ehlo, but it is not logged. This is one of the lists effected, so please include a Cc to me.
