Thanks for response... but this virtusertable will not stop SMTP server in internet to keep send you undeliverable message. I assume someone doing nasty with forged and use my domain email to send his spam message to non existing user. and i got undeliverable message. Is there any clue ?? Oh.. i forget to mention i use 4.11-STABLE for my MX regards Reza _______________________________________________ email@example.com mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
