Ignorant of exactly how Postfix accomplishes this, I'd imagine it would go something like this: You receive a spam message from [EMAIL PROTECTED]'. Before accepting that message, your Postfix queries hotmail.com's SMTP server to see if `bogus' is an invalid address (i.e, if mail to [EMAIL PROTECTED] would bounce). If so, it rejects the message, otherwise it allows the message to be delivered to you. In essence, only messages which can be replied to will be allowed through, which makes a lot of sense to me. This would significantly cut down on the amount of spam TMDA would have to process, and also the number of returned confirmation requests.

I disagree, since as I explained, this is only reliably done at the MTA level. You'll inevitably lose legitimate mail if you attempt otherwise. Not only that, but it's more efficiently done at the MTA level as well since the verification process would be much less expensive there. _________________________________________________ tmda-workers mailing list ([EMAIL PROTECTED]) http://tmda.net/lists/listinfo/tmda-workers
