Couldn't open SMTP server 127.0.0.1:25!

[Aziz Manas]

I'm running Redhat 9 with OpenWebMail installed. When i try to send email it
got this error message from OpenWebMail
Couldn't open SMTP server 127.0.0.1:25!

I need some assistance on this area since I just recently installed
OpenWebMail for my office intranet server.
Thank You.
