I tried to CREATE the mysterious "block of random characters" and had some
success.  Some list members write a message using MSWord or some such, then
insert it into their email after.  Purely a writers preference, but a
combination of "special" controls from a word processing app. and the
browser SENDS the block of random characters, which then is seen as garbage
when reading.

Or at least I think that's what's happening.
