[sendmail] Skipping rbl per domain

[Aaron K. Moore]

If you are hosting individual e-mail accounts, then you should give
milter-ahead a second look.  All it does is verify that the recipient's
e-mail address really exists by querying the internal mail server
hosting the domain.  If it does not exist, then it rejects the e-mail.

That way you're not chewing up processing time with MailScanner scanning
e-mails that are only going to be rejected because the account doesn't
exist.  

I used to have a lot of those messages clogging my outbound mail queue
on my MailScanner box until I started using milter-ahead.
