Bogus.
Joe-jobbing is a problem whether C/R exists or not. If someone decides to send an email to 100,000 known bad addresses, and uses the your address in the "From:", "Reply-To:" and envelope sender address, you're going to get 100,000 bounces whether or not C/R is in place. Any email system that returns error messages through email (including TMDA and sendmail and postfix and MS Exchange and...) will cause joe-jobbing problems. True - C/R doesn't solve it. But it's hardly the cause of it. And, as others have noted, if everyone is using C/R in the same fashion that TMDA works, then joe-jobs stop working altogether. $.02 - Mark _________________________________________________ tmda-workers mailing list ([EMAIL PROTECTED]) http://tmda.net/lists/listinfo/tmda-workers
