[Mimedefang] OT: How to keep sendmail from using /etc/passwd

[Kevin A. McGrail]

I think what he might be looking for is the virtusertable/aliases/sendmail, 
do-not-expand "trick".

mike at domaina.com   \mike
mike at domainb.com   \mikey

The \ means deliver to that account and do not expand, use aliases, etc.

KAM
