Does such a mailer (i.e., Netscape 7.1) display and extract it
correctly?  If so, Gnus will have to somehow do it, too.  I don't
believe any mailer always can do it, though.  Anyway, he probably
sends such ones not only to his men but also to his bosses, so he
will lose his post sooner or later.  It's only a matter of time.

Although efforts to fix it might all go for nothing even if the
problem is simply that exactly the "=?=" is always lacking, could
you show the raw header of the part in question?
