[Mailman-Users] Firewall

Finally i have resolved all previous issues. Mail is being sent, recieved
etc etc
(the /var/log/mailman/error was chmod to 644 by default i changed it to 664
and web interface started working)

Now i have turned on iptables (no point having it on during testing) and
now outbound mail is stuck in the sendmail queue with host map: lookup
(xxxx.com.au): deferred

If i turn iptables off all mail is sent instantly - i can recieve mail with
it on or off, no problem.

I would like to run iptables on, and poke a hole for the DNS lookup (i
assume this is what it is?) but i dont know exactly what i need to do, does
anyone how to turn off this feature in sendmail, or which port i should
allow in the firewall? i am happy to apply either as mine will be a fairly
low volume list.

Thanks in advance
