What is it you're trying to verify?  Telnet will allow you to check to see
if the destination SMTP host is responding and processing messages
correctly.  For internal communications there is a utility called RPCPing in
BORK.  It is similar to the regular "ping" but verifies RPC communications
between your servers.  

On the other hand if you're trying to validate incoming messages (as in
making sure a message from a yahoo user indeed comes from a yahoo mail
server), then you're looking into performing a reverse DNS lookup.

Subject: email validity


Is there a way to check to see if an email is valid, without sending an
actual test email? Something like ping or telneting to the mail server and
checking?
