An additional sendmail ruleset stops SMTP transactions with MTAs that 
HELO/EHLO as our MX, with this message: 
          "ruleset=check_rcpt, arg1=<recipient_address>,
           reject=554 5.7.1 Invalid helo rejected; send mail to
abuse at 
           if rejected in error - are you really"
which stops even more _and_ gives me nice patterns to watch in my
database. But all that's off-topic here, so ask in private mail if you
want more info. 


I'd like to hear more about that one :)
