Thanks for the suggestion, Gerald. I was hoping for something more ... *honest*. To claim successful delivery and silently discard a message is a lie. The legal term is *misrepresentation* and I am eagerly waiting for the client coming through my door who has been damaged by an email service operator that replied with a 250 and then silently discarded the message. It is one of the main reasons why we lawyers continue to use fax transmission: the protocol is reliable, my fax device receives the equivalent of a 250, I can rely on the fact that something has been delivered. Not silently discarded. As for the other comments elicited by my post: is there any evidence that Google stops sending ALL mails on some very specific rejections? or is this just FUD? After all, Google is used by millions of senders, and some of them are most obvious spammer. Does anyone expect an email server to accept an email containing a request to send money by Western Union to some exotic country in exchange for the prospect of receiving an inheritance from an obscure prince or despot of said country? Thanks, Yuv
