I would focus on your reject_unauth_destination setting in postfix. See http://tinyurl.com/499ro for more info.

I am noticing entries in the maillog like the following. This tells me that somehow mail is relaying through my system. I followed the Scott Henderson setup document and havent noticed this before. Jan 11 11:24:33 SA2 postfix/smtp[12722]: 8FE98F4280: to=<[EMAIL PROTECTED]>, relay=milter1.store.vip.sc5.yahoo.com[216.136.232.238], delay=22, status=bounced (host milter1.store.vip.sc5.yahoo.com[216.136.232.238] said: 550 5.0.0 <[EMAIL PROTECTED]>... <[EMAIL PROTECTED]>: User unknown (in reply to RCPT TO command)) Here is my postfix main.cf alias_database = hash:/etc/postfix/aliases myorigin = georgetowncollege.edu myhostname = sa2.georgetowncollege.edu mydestination = georgetowncollege.edu mynetworks = 10.1.7.0/24 biff = no smtpd_banner = sa2.georgetowncollege.edu # Message limit at 20MB so that daily spam reports can get through message_size_limit = 20000000 # Added error: in front of no local mail delivery 092104 local_transport = error:no local mail delivery local_recipient_maps = transport_maps = hash:/etc/postfix/transport smtpd_helo_required = yes #smtpd_helo_restrictions = permit_mynetworks, reject_invalid_hostname, reject_maps_rbl smtpd_helo_restrictions = permit_mynetworks, reject_invalid_hostname maps_rbl_domains = sbl.spamhaus.org, relays.ordb.org, opm.blitzed.org, dun.dnsrbl.net, spam.dnsrbl.net smtpd_sender_restrictions = reject_non_fqdn_sender, reject_unknown_sender_domain smtpd_recipient_restrictions = permit_mynetworks, reject_unauth_destination, reject_non_fqdn_recipient header_checks = regexp:/etc/postfix/header_checks content_filter = smtp-amavis:[localhost]:10024 Is there something I need to change ? I am not seeing this a lot and thought I needed to look to see if I could find the problem. Any suggestions would be appreciated. Ron
