I'm running sendmail and MailScanner also.  I've recieved outstanding
support from the MailScanner listserv.  Send an email to:
jiscmail at jiscmail.ac.uk with "join mailscanner your-first-name
your-last-name" in the body (sans quotes).  I'm sure they can get you up and
running in no time.

Best of luck,

Christian
