I am having problems setting up the outgoing mail server to successfully send emails through our relay server.

I am able to successfully fetch mail with IMAP protocols, but sending is providing me with a connection refused error.

We have checked with our Server team and port 25 is open, but I'm receiving a connection refused error.  We can also successfully telnet from the host machine to the mail server.

I have sent a support file to your support@supportcenterplus.com email address.

Can you please provide assistance.

Thanks

Jami
