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 regards Reza _______________________________________________ firstname.lastname@example.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
