They're using a greylisting "technology"... It forces the sending SMTP server to be delayed (read the message) as it sends a 450 which is a temporary error message. Your sending mail server SHOULD attempt to resent at a later time (though you don't have control over it). The sending server suggests 600 seconds, while the sending SMTP server won't likely read past the 450 part. People are trying this as an anti-spam thing, as most spamming software connects directly to the recipient mail server, and has little respect for RFCs, and as such would ignore that message, so the mail would be dropped. If your SMTP server follows RFCs, then it would have been retried at a later time, and delivered. -- Jonathan Angliss ([EMAIL PROTECTED]) Using The Bat! v2.11 Beta/6 on Windows XP 5.1 Build 2600 Service Pack 1 Bad command or file name.
