Setting up valid recipient lookup lists at
the edge mx’s go a long way, Postfix with getadsmtp.pl for
relay_recipient lists works really well for those of us with user bases in active
directory Modify maxpagesize policy using ntdsutil.exe
to increase page size from default 1000 records when required, For those of us not using exchange, the
filters in the perl script need to be tinkered with to pull the records you need
from ad. This is only but a small portion of an
entire mailserver setup, and is a hint of what I had done to solve my issue
with backscatter. Hope this helps, Chan From: pacnog-bounces@pacnog.org
