User? On our boxes it returns an appropriate error code to the sender (who is the only person who can fix the issue), and logs an error. I use logcheck and pflogsumm, so as administrator this is picked out of mail logs and reported to me. One could create an event from the log file entry, plenty of tools to do that sort of thing around, but I'd say half of these events are things the users wouldn't want to know about anyway (i.e. things (read bots) gone mad, rather than genuine attempts to send email with big attachments, although that may depend on the largest size allowed).
