Using sendmail to redirect selected email

[William Burns]

Steven:

I use the LDAP "Laser" standard to query an external LDAP database, and
route mail accordingly.
This is working very well w/ over 2000 users.
There is no delay that I've noticed for additional users.

Other people have pointed out (and it's in the mailscanner FAQ, or MAQ
somewhere) that a sendmail "LDAP" query can be done to a local database
file. That way, you don't have to configure an LDAP server.
