It seems like mail sent to me gets stuck in the deferred que. What happens according to the log file is that the av software receives it then tries to resend it to my external IP (im behind a NAT firewall) It then times out.
status=deferred (connect to xxxx.biz[xx.xxx.xx.xx]: Connection timed out)
(private info xx'ed out)
My problems started after i checked "Enable DNS lookups". Before i did that i couldn't send mail out, but received just fine.
I tried following this "http://www.tickus.com/?q=node/15" (i use ubuntu 6.10 ) to setup BIND, but host xxxx.biz still resolves to my external IP even though all other nslookup or ping i do resolves to my internal IP.
Any help appreciated.

telnet xx.xxx.xx.xxx 25

Obviously working, so why can't i send mail?
