Sure you can. If Alice wants to legitimately contact Bob from a blacklisted IP (whether the blacklisting is actually Alice's fault, or she's just fallen under an excessively large blanket), and Bob is running DNS-based filtering, Bob's MTA blocks Alice based on her IP. Bob loses legitimate mail. Admittedly you provided a counterexample, but it is not always so easy. -- Paul. mailto:[EMAIL PROTECTED] mailto:[EMAIL PROTECTED] _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
