What I didn't like is that the MTA becomes the strictest enforcer of
"content", and that "SPAM filtering" rejects not SPAM but messages that
it [the author of the SPAM filter] thinks are syntactically incorrect.
For instance, looking for characters with bit 8 set must be _the_
anti-SPAM measure with the lowest sensitivity and specificity. It does
work reasonably as a filter against Swedish E-mail, though (sensitivity
5%, specificity bad).
