Can't.  You have to send the 5xx response before any message data,
including headers, is even sent.  By the time they've sent the whole
message and you get to tokenize it, the spammer has moved on to the next
victim.  If they don't care about bounce mail they're not going to care
about 500 errors after they've sent the entire message.
