can't connect to smtp

Hi,

I'm new to his webpanel, and use to work on Plesk for my professional servers…

I can't achieve to connect to the smtp, telnet keeps telling me "Operation timed out" on port 25. Ports 465 and 587 seem to be completely blocked.

My version of centos is the 6.5 and everything comes from a fresh install… The domain name and DNS settings have been correctly parametered (i guess). If it can help, the domain name is kodingkittens.com (yes, i know, kind of funny  ). Postfix seems to work fine too… many services have been restarted again and again, and nothing !

Thx for any help !

try disabling CSF firewall, maybe you have blocked ports if so than white list port you require

I forgot to say it, but i already tried this !… and nothing changed

nmap returns that :
25/tcp    open  smtp

and netstat :
tcp        0      0 0.0.0.0:25                  0.0.0.0:*                   LISTEN      23664/master       

Are you achieved that?
