Eamil from invalid users in own domains???

[Alex Neuman]

How about requiring SMTP authentication? That would impede inexistant users
from using you to relay.

Oh, and how about not using web bugs in your e-mail? ;-)

Is there a rule or how would we  or can we create a rule that will B/L email
addy's from invalid users on the domains which are being hosted?

We currently whitelist our domain, but would like to workaround for unknown
users...

Currently using Postfix, and this may be a postfix or procmail issue...

Latest SpamAssassin 3.00000, latest MailScanner, etc...
