Hai friends

We have one major problem in our dedicated online mail server.
In this mail server both sendmail and qmail running for send and receive mails.
In this server I can able to send mail to other domain like Gmail and yahoo its works fine.
But I am not receiving any mails from other domains. And automatically I got telnet localhost 25 connections refused error. When I send mail from my webmail I got like this error Connection refused Server replied: 111 can’t open SMTP stream. This is I got when I send mail from webmail. I am using centos 5.2 version.

Make sure the service is running.
Make sure port 25 is open on the firewall.
Make sure port 25 is open and forwarded at the router to the server.


Kind regards

Thanks for the reply.

I will check the port 25 open in server but suddenly when i check telnet localhost 25 i am getting connection refused error. so i restart sendmail service after restarts telnet localhost 25 working fine. i am very hard to understand what happen in server so please advise me.
After restart sendmail its shows like this with in a minites.
