Topic: connect from unknown

This is a new installation and I am trying to understand what it takes to get iredmail going before I go put a server into production.
while looking at the logs I find that ALL incoming email from all servers will have a log entry like this.
The actual servers are fully qualified so I don't understand why it say "connect from unknown"
do I need to configure some dns server that is not properly configured? the machine itself resolves everything OK.

May  3 17:42:52 ired postfix/smtpd[2899]: connect from unknown[74.125.82.169]
May  3 17:42:54 ired postfix/smtpd[2899]: 427F8A806CF: client=unknown[74.125.82.169]
May  3 17:42:54 ired postfix/cleanup[2907]: 427F8A806CF: message-id=<CAD=SNO_fADf+H2pwnaWPi9BFzTjcvuZo3U_dD56QgCbAQdBuxA@mail.gmail.com>

Re: connect from unknown

This is a known issue, Postfix cannot resolve IP address.
The solution is, coping /lib/*nss* and /lib/*reso* to /var/spool/postfix/lib/.
If you're running x86_64 edition, copying /lib64/*nss* and /lib64/*reso* to /var/spool/postfix/lib64/.

Restart Postfix, then it should work.

This fix will be available in upcoming iRedMail release, 0.8.7.
