The way I read RFC822 (and 2822) is that if an MTA is going to reject a 
message it should do so as early in the transaction as possible.  It should 
never accept a message it will not deliver.  So, if Exchange is dropping 
the message after the final "dot+<CR>" due to a malformed or rejected 
address, it should have done it during the "MAIL FROM:" or "RCPT TO:" 
stage.  IOW, I believe this violates the RFC.  But hey, it's Micrsoft - 
since when to THEY care about published standards?!?

Cheers,

James
