RE: CNAME, iptables and qmail
Damn!! I hit send before editing this message. Sorry!
Please read this instead of my previous message.

I'm setting up a Deb (woody) box with qmail and iptables.
I've got both installed, both seem be operating fine.
Iptables is setup to no allow traffic other
than 25, 110 and of course 22 (ssh).
The problem I'm running into is iptables is causing
e-mail to be NOT be sent (smtp) through the server and I get
this message in the /var/logs/qmail/current file:
@400000003cd6d8d41f84ee7c delivery 47: deferral:
CNAME_lookup_failed_temporarily._(#4.4.3)/
When I flush iptables, of course it works and I can send and
receive fine (via SMTP and POP3)
Anybody know what the deal is? I suspect some DNS ports need
to be opened up, but I'm not sure...
Any suggestions?
Gary
