It's Wed, Dec 20, 2006 at 09:26 . I'm in a small dim room with doors labeled "Dungeon" and "Forbidden". There is noise, the door marked Dungeon flies open and Beastie MRA SHOUTS: > Dear All. > > For past few days, my MX receive thousand of undeliverable message > destinated for my non existent user at my domain. > This message source come from valid and well configured (almost) smtp > server on internet. > I'ts waste my internet b/w, cause my MX will reject with non existent > user message. > I'll try spamd on my firewall and greylist on my MX (postfix), but still > no effective, and i cannot block undeliverable > message as RFC rules > > Is there any way i can fix this ? > Please help I use the virtusertable in sendmail, and I have my valid addresses, such as bv@wjv.com bv and then for after that is a line of @wjv.com nouser. And nouser is defined in aliases as nouser: /dev/null On one of the mail servers I maintain I just checked and I had 260,000+ messages routed to "*file*" in the maillog - which shows up as mailer=*file* in the logs. That maillog rotates every night at midnight. Is not really a freebsd-net problem so I removed that from the reply to line. Bill -- Bill Vermillion - bv @ wjv . com
