Hello Roelof, RO> Consider redirected mailboxes etc. Depending of the way the RO> encountered MTA's function the receipt confirmations can get sent RO> multiple times.
Well, normally, the receipt should be received only once and it should not tell whether the message was further redirected and to which address. RO> Apart from that, confirmation of receipt by an mta is also RO> confirmation that the used e-mail address is valid. So down the drain RO> with the option of not responding to spam in order not to validate the RO> address. There are other FAR MORE sufficient ways of e-mail validation. Waiting for confirmation receipt means receiving one message back. Imagine one million of addresses validated this way - it's one million of receipts to receive and to process. It's a bit more complicated than just spamming away :-) RO> Everything that validates my address without that validation being RO> initiated by me is a privacy issue. Usually, e-mail can be validated by simple sequence: HELO/EHLO MAIL FROM:<> RCPT TO:<youraddress> -->Your address is almost valid if a positive response is received here RSET QUIT AFAIK, this is what address verifying programs are doing. Surely enough, they are checking MX records to reach the final destination... So, e-mail is really privacy-demolishing tool ;-)) I think the best way to get rid of SPAM is to get people to sign messages using PGP or S/MIME and consider only signed content. Well, it's a dream, you know... -- Read you later Stefan ..."Be happy.
