sendmail settings. set dns entry so relay has lower mx mail record then internal machine.
then set machine to relay based on mx. FEATURE(relay_based_on_MX)dnl then set mailertable settings. FEATURE(`mailertable')dnl /etc/mail/mailertable: #domain to accept mail for and mailserver #don't consult dns to determine how to relay coe.montana.edu esmtp:[power.coe.montana.edu] then set bounce define(`confDOUBLE_BOUNCE_ADDRESS', `root') then set to keep addresses that are in + format. dnl keeps the + and does not expand alias FEATURE(`preserve_local_plus_detail')dnl My other advice is this. If it is the only incoming mail relay, I would verify thus. Have a slower secondary mx backup mail server. Make sure management/users are notified of what attachmeents you will block and subject/content mungting you will do based on spamassassin. In my relay configuration I don't modify ANY subjects or content, I just add x-headers and let clients handle. Becasuse we also have internal spam programs that would not work correctly if the content was changed. -- Luke Computer Science System Administrator Security Administrator,College of Engineering Montana State University-Bozeman,Montana _______________________________________________ Visit http://www.mimedefang.org and http://www.canit.ca MIMEDefang mailing list [EMAIL PROTECTED] http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
