Unfortunately, THOSE may be a bit too simplistic :( Someone forges an email appearing to come from one of your honeypot addresses, and sends it to a bogus (or on-vacation) address at a legitimate site. The bounce (or vacation response) comes to your honeypot address, causing you to blacklist the legitimate site. No, I am not making this up. More than once I've discovered one of my employer's mail servers on the Spamcop blacklist, causing my home upstream to bounce (as presumed spam) messages I tried to send from office to home. This seemed to have been the mechanism involved. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
