Unknown user again

[Bill Anderson]

When you say local db file, are you refering to the accessdb file in
sendmail?  So, if I can paraphrase what you just said.  Using some sort of
script that get's a list of emails from the various email servers, some
LDAP, some not.  Compile this list into an accessdb file for use by
sendmail?

Is there anyway to have sendmail / mailscanner drop 550 errors it receives
from the other mail servers?  I want to fix my short term problem.

Thanks.
