mail relay / spam

[about]

I used exchange 2000 (sp3), ISA 2000 (SP1) and windows 2000 (sp3) for a small company. (20 users).
I think we have spam mail, the badmail map is full.
and in the exchange system manager under SMTP, Default SMTP Virtual server, queues there are strange queues (sex sites)
The mailserver is checked on mail relay => and that's ok (checked by

http://www.ordb.org)

We used a smtp connector, for the smtp mail

Who can tell us how we can prevent this spam mail

thanks

Prevent, no.
Get rid of them, use a spam filter, or, forward all unrecognised addresses to a Junk mailbox and delete. _{If the answer is here, mark it, others can benefit from it too. If 'something' 'somewhere' gives 'some' error, excpect random guesses or no replies at all. Please specify details.
