Here's some information which Ellen has posted in the past re smtp/auth
when she looked at evidence:

<Ellen quote>
Your exchange server is
relaying spam for spammers. It appears that your exchange server is being
used by spammers exploiting the SMTP/AUTH hack. Please see this faq for
information about the exploit and how to fix the problem:

http://news.spamcop.net/cgi-bin/fom?file=372
http://www.winnetmag.com/article/articleid/40507/40507.html
http://www.winnetmag.com/article/articleid/42406/42406.html

This exploit allows spammers to relay thru your exchange server. This
relaying does not show up using standard open relay tests as the spammer
has
gained "legal" access to your server by hacking an account/password
combination.

I didn't know this about the exchange version nos snipped from the 372
faq above:

"At first glance that does look like MS Exchange 5.0, but tracing the
version number through the Microsoft website we find this is really
Microsoft IIS/5 service, which is included as part of Microsoft Windows
2000 Professional and Windows 2000 Server."
