i have an Ubuntu server with Postfix, Courier and mysql. I have configured SSL/TLS but my mail server is not listening on port 993 and 995 (well only for tcp6 and not tcp) hence I cannot connect and authenticate with SSL/TLS protocol.
I have tried adding them via the iptables:
iptables -A INPUT -i eth0 -p tcp --dport 993 -j ACCEPT
iptables -A INPUT -i eth0 -p tcp --dport 995 -j ACCEPT
and still nothing...
