Debugging SMTP send problems

Folks:

Can anyone point me to a manual or a log file / queue that will help me
debug SMTP send problems?

I'm trying to use the SNDDST command to send internet email messages,
and I get the following response :

> HOST SILVON10 NOT ABLE TO DELIVER MAIL TO FOLLOWING RECIPIENT(S):

>    <david.gibbs@MKS.COM>

> RETRIES EXHAUSTED WHILE ATTEMPTING TO CONNECT TO REMOTE HOST MKS.


I'm able to telnet into the MX exchanger for mks.com on port 25 (SMTP),
so I know it's responding... but mail sent from the '400 doesn't seem to
want to go.

Thanks!

david
