Email not working for both send and receiving

Hello Everyone,

In my virtualmin server everything is working perfectly so far except the email. In my server I am unable to send or receive email.

whenever i go to the mail queue i can see connection timeout error.

Is there any suggestions to fix it.

Thanks for your help.


Are other services, such as Apache and SSH, working as expected?

If so, is it possible that your provider is blocking access to port 25? Not all providers allow traffic on that particular port, in an effort to cut down on spam.
