I have been having a problem with my cpanel install where i can only send e-mail by connect to the server by SSL. While this is a good thing for the most part i do not currently have a valid SSL cert so i get a warning by all my apps. It also has stooped some of my websites to stop sending e-mails because they get stuck on the unsigned ssl.

When i try to connect to my SMTP server over port 25 it just sits there tell it times out even with the firewall off.(Accepting all connections)

I do not know where to look for errors that would have to do with this.


Thanks in advance for any help.

Hello :)

It's common for Internet service providers to block access to port 25. You can contact your web hosting provider to see if they have an alternate port enabled for SMTP. Many hosting providers will enable port 26 as a solution to this.

Thank you.

Your access level is listed as "Website Owner". Could you confirm if you have root access to your server? If so, please run the following commands to see if Exim is listening on port 25:

Code:
# netstat -lnp | grep :25

# exiwhat
If you do not have root access to the server, please contact your web hosting provider for assistance.

Thank you.

Exim is running and listening on port 25
Code:
tcp        0      0 0.0.0.0:25                  0.0.0.0:*                   LISTEN      18227/exim
tcp        0      0 :::25                       :::*                        LISTEN      18227/exim

What result do you receive when you attempt to telnet from your computer to your server over port 25?

Code:
# telnet yourdomain.com 25
Thank you.

Ok, I did find out that my isp stared blocking port 25 about 6 months ago so that is my problem....rely need to read their e-mails. So how do i change my SMTP to work on port 26 ?

Edit: NVM found the setting under the service management.

For anyone else who may need to enable Exim on another port, it can be done via:

"WHM >> Service Configuration >> Service Manager"

Thank you.
