There's one type of sender that will fail horribly in interpreting that reject message: the automated type. Particularly, mailinglists. Suppose someone runs a "controversial" mailinglist which happens to get flagged as spam a lot. Some of your users notice and either disable the spamfilters or "greenlist" the mailinglist so it won't be spamfiltered, but not all subscribers at your site do. Then when the mailinglist next sends a "spammy" message, and suppose it will send to most subscribers on your domain using a single message, that message will get a 550 error after data, which might lead to ALL subscribers being removed from the list... even though the message said something like "550 successfully delivered to <[EMAIL PROTECTED]> and <[EMAIL PROTECTED]>, but rejected by <[EMAIL PROTECTED]>." Drusilla and Xander would still be out of luck... -- Jan-Pieter Cornet <[EMAIL PROTECTED]> !! Disclamer: The addressee of this email is not the intended recipient. !! !!
