Hello,
I use postfix+clamav-milter on Debian 4.0 and I noticed following error
messages in the log:
postfix/smtpd[26955]: connect from mx1.atlascz.net[194.212.229.235]

It happens only from time to time (once per cca 1000 delivered
messages). It seems that at least some of failed mails are successfully
delivered a bit later.
These errors started after upgrade from Clamav 0.90 (stable) to Clamav
0.91 (testing). I tried to upgrade Postfix as well (from 2.3.8 to 2.4.6)
but it didn't help.
Please try 0.92, some changes were made which may help. We couldn't reproduce
the problem, so I'd like to know if the 0.92 changes have helped.
Any idea what's wrong or how to fix it? Thank you very much in
advance.
-Nigel
