If this became widespread, then a lot of ISPs would need to set their = SMTP servers to retry a lot more often. Otherwise, customers would complain about the email delays. Also, if it were widespread, spammers would = simply double tap each email. Sending the exact same email twice instead of = once would get the spam through the Greylist filter. And by requiring such, = we would only be encouraging more bandwidth wasting. Greylisting is, at = best, only a very short term solution. As soon as it became popular, it would = no longer be useful.
What I would like to have more than anything right now is SMTP-SASL, so = I could fully implement SPF. Right now, I have no way of opening another = SMTP port for only SMTP AUTH connections. I want to open 587 for SMTP but = only SMTP AUTH. That would do me world more good than Greylisting. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] = On Behalf Of Davide Libenzi Sent: Friday, December 17, 2004 3:31 AM To: XMail mailing list Subject: [xmail] Graylisting ...
