No. Greylisting (or graylisting) is a method of defending e-mail users against spam. A mail transfer agent (MTA) using greylisting will "temporarily reject" any email from a sender it does not recognize. If the mail is legitimate the originating server will, after a delay, try again and, if sufficient time has elapsed, the email will be accepted. If the mail is from a spam sender, sending to many thousands of email addresses, it will probably not be retried. Greylisting involves sending a temporary 451 SMTP error code to the sending server when a message is received, along with sending this error code ASSP creates a Triplet and stores this. On the second delivery attempt if the Embargo Time set by the ASSP admin for the Triplet has been surpassed the message will be accepted and a Tuplet will be created and not delayed again for an Expiry Time set by the ASSP admin. ------------------------------------------------------------------------------ The Palm PDK Hot Apps Program offers developers who use the Plug-In Development Kit to bring their C/C++ apps to Palm for a share of $1 Million in cash or HP Products.
