It's a little bit off topic,
but does anywhere know which ports to open on my firewall so that
qmail works correctly.
25 outbound if you only want to send e-mail to external sites. 25
inbound as well if you have a mail server in a DMZ.
At the moment I've opend dns,smtp and pop3 but when i activate the
firewall some messages can't be delivered (wasn't able to establish
an smtp connection),
Log entries? Kernel details? OS even? There is a big diff between
Linux and FreeBSD. Hec, there is a big diff between Linux v2.0, v2.2
and v2.4 firewalling. How are we meant to help you if we don't even
know the foundation?
but when i try to telnet to the specified rcpt-server everything
works really fine.
rcpt-server = really crazy parrot tarot-server? What do you mean,
rcpt-server? Do you mean the remote MX?
So what happend here ? (if i open the firewall for everything, then
the messages are leaving the queue)
Nice... I think it's probably safer you leave the firewall
