That's the one.  I used to test SMTP stuff by using telnet to port 25
and talking to an SMTP server, but swaks does all the lifting for you,
and gives you a terminal display of the entire dialog in real time, so
you can see where a SMTP transaction is hanging, or timing out, or
whatever.  It's written in perl, and self-docs with a man-page like help
system.  It has a ton of useful options, and is truly, as advertised,
"the Swiss army knife for SMTP".  As a mail admin, I couldn't be without
it :)
