RFC 1522. Whether you'd want to open that can of worms
by decoding headers in that format to some other character
set for email is a good question (especially as a lot of spam
has headers that end up containing illegal characters if
you do that).
If you were to do that you'd probably have to deal with
i18n domain name encoding too, which is even more hideous.
Fortunately all this stuff is MUA-side, not MTA-side, so exim
should ignore it. SQL_ASCII all the way.
