SV: RCPT TO: rejecting

I've found that connecting to the mail server of the MAIL FROM:
address and attempting to initiate an email (up to the DATA stage)
successfully detects around 30% of all my "joe jobs" spam

shouldn't this be part of the wider scheme to prevent joejobbing ?

No. This would make it extremely easy to make a distributed
denial-of-service attack againt a mail server.

Lars.
