Hi all,

I have installed and configured Postfix and Dovecot in CentOS6, I have
followed this tutorials:

Postfix, http://www.server-world.info/en/note?os=CentOS_6&p=mail&f=1
Dovecot, http://www.server-world.info/en/note?os=CentOS_6&p=mail&f=2


What can I do to try to solve this? Please give me a clue.

Best Regards,

The default configuration of Postfix on CentOS6 specifies to only listen on localhost. Make sure that you've set inet_interfaces to "inet_interfaces = all" to ensure that postfix listens on all IP addresses. Alternatively, refer to http://www.postfix.org/postconf.5.html#inet_interfaces for more specific parameter documentation.

-A INPUT -m state --state NEW -m tcp -p tcp --dport smtp -j ACCEPT

Also make sure that you've allowed port 25 in your firewall. If you're using the default CentOS iptables firewall, add: with the other similar looking lines, then do "service iptables restart" to apply the changes.
