   Nope, don't have that issue.

   OK, good.

  OK. Ordinarily I'd agree with you. However, an analysis of 10 YEARS of
collected E-Mail has shown that 6 of those character sets are *only*
associated with SPAM. Only the "windoze-125x" sets show up in any of my
HAM, and then its very little - and I can drop those two sets out of my
auto-reject list.

  And MD already technically violates RFCs. I think that worrying about
this idea violating the spirit of an RFC "should" clause is like
worrying that the finish on my new anti-burgler deadbolt lock violates
the HOA-approved color scheme.

  That is my objective - to ditch the garbage as early as possible. If I
can avoid invoking SA and reliably kill SPAM, that's fine.

  Thanks to everyone for their feedback.
