directory harvest attack

[Craig Pratt]

I presume he's talking about collection of addresses in a domain by
opening an SMTP session and attempting sends to common/dictionary names.

I just happened to notice some of this activity in my mail log and
added a reject action for the sender's IP to the sendmail access db. To
automate this would be cool - but I don't think MailScanner even sees
the message - based on how these harvesting tools seem to work.
