iredmail/Ubuntu can't connect client's to smtp server
 
Well, roundcube webmail works great. I even added a calendar. My clients love it.
However, whenever I try to sync a device or computer to it via outlook, I get a "Cannot connect to outgoing server" error. Pop3 works fine, but as for sending stuff? I get no love.
I've verified the correct firewall rules:
Quote:
-A INPUT -p tcp --dport 25 -j ACCEPT
-A INPUT -p tcp --dport 587 -j ACCEPT
and in dovecot.conf
Quote:
listen = *
is uncommented. Any idea on how to handle this?

Does it make any difference if you add a few options to your iptables rule?

-A INPUT -p tcp -m tcp -m state --dport 25 --state NEW -j ACCEPT
There's a 'LOG' option for iptables that may help you troubleshoot.
