[Mimedefang] Enumerate Email Address parts

[Kevin A. McGrail]

It sounds like you are trying to get the local user and that you are 
assuming the first half of the email address is the username.

Instead, might be worth a caching system that uses sendmail -bv to 
verify it's a local user:

For example, sendmail -bv kmcgrail-test at pccc.com               
kmcgrail-test at pccc.com... deliverable: mailer local, user kmcgrail

P.S.: DFS is an optimist.  I was thinking more like a thousand things 
that can go wrong.
