Very likely true, if I am the only one doing this. I _am_ sort eyeing
the idea of writing up an "SMTP-time spam filtering HOWTO" in the near
future, wherein I could suggest someting along these lines. If enough
people are doing something similar, such local_part_suffix combinations
of addressess would soon make it onto ratware delivery engines..

If such MTAs exist (which I doubt, as far as the major players go),
they deserve what they get.    MUAs sending replies to the envelope
sender would not be a problem - the mail would get delivered anyway.
("local_part_suffix = +*").
