Ok, I think I was mistaken in where the denial message was actually generated.
If I understand you guys correctly, my server give the 550 to the delivering server and if it's a spammer hes just going to ignore it and move on. If its a legitimate email server THAT server is the one generating the email back to ITS sender notifying them of the error. Is that right?
