One of my server affected by spammers the using a login id and password one
of mys user and sending mail via other mail ids.
Some of your honest users need to send mail with another email address
in "From:". For example, *-owner()yahoogroups.com, @ieee.org.

That will block most customers, who try to send valid newsletters :) 10% or more of the address database of those newslettersenders is invalid and old addresses.
