[Mailman-Users] Firewall

[Peter Russell]

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

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

Thanks in advance
Pete
