I disagree strongly (assuming we remove the noise word "randomly") Attempting to deliver to nonexistent recipients is by far the most common cause of backscatter, and doing an SMTP call-forward on the ultimate destination is a simple and cheap way to avoid this. Your point about post-DATA rejection is valid, but this makes up a very small percentage of backscatter. -- David. _______________________________________________ NOTE: If there is a disclaimer or other legal boilerplate in the above message, it is NULL AND VOID.
