OT: Dynamically updating /etc/mail/access

[Andrew M. Hoying]

I implemented this and a few other things in a script and now we are
blocking 80%  of incoming spam without having to bother MailScanner or
SpamAssassin with processing it.

Spam Caught / Total Incoming E-mail:
444 / 3103
High Scoring Spam:177
Spam blocked by sendmail:1748
