OT: Scanning outgoing mail

[Billy A. Pumphrey]

Will someone point me in the general direction of what needs to be done
to scan outgoing mail?  I do not really know what to do.  

I use MailScanner as a gateway to exchange.  I am guessing that I need
for exchange to send the email to MailScanner and from MailScanner to
the internet?

Would MailScanner use the same SMTP sendmail to send out the mail?
Thank you
