How to open Port 25
[Not Solved] How to open Port 25
Dear Friends,

I have installed Sentora on CentOS 7 (minimum install 64 bit).
I'm however unable to send emails while I can receive them.

It was working fine earlier and it stopped when tried to upgrade to CentOS 7.

Attached is the screenshot where it says, SMTP Port 25 is Closed.

I really appreciate your help in this regard.

Thanks in advance...

Best Regards,

Port 25 is open by default check with your ISP as it's likely he is blocking it.

No support using PM (Auto adding to IGNORE list!), use the forum.
