This goes against the old principle of being forgiving in what you
accept, and strict in what you send.  The names of the encoding in the
headers should probably be normalized before putting them in an
e-mail.  I.e. we might accept "utf-8", "utf8", "UTF-8", and "UTF8"
(this depends on iconv, I suppose), but the RFC2047 encoding should be
the one blessed by RFC4027.  But I admit that I haven't read the RFC,
and I'm writing this offline so I can't check right now.
