Can you in Terminal, establish a Telnet session with the remote mail server?


ie. If your smtp server is mail.mydomain.com, then in Terminal, type

Telnet mail.mydomain.com 25

You should get some type of message like:

220 xyz.mydomain.com ESMTP server ready

If the above 220 message looks friendly, then type:

helo mail.mydomain.com       ; (that is purposefully 'helo' without 
the second l)

You should now get something like:

250 xyz.mydomain.com hello [<Your IP Address>], pleased to meet you

or something friendly again.

If you get some response from the smtp server that is less than 
friendly, post back with that message.

To exit the Telnet session, type Control-]   (Hold Control & type the 
right square bracket)

Then type Control-c
