I agree that that's illegal and we shouldn't do it.

This is just depressing, because like, they went out of their way to do
it wrong. Sigh. Anyway, what are the odds that someone would actually
name their file "=?iso-8859-1?blahblahblah", so yeah, I guess we can
decode that. Sigh.

4 cannot be interpreted that way generically because you don't know what
character set it's in.

Anyway, yes, we should generate RFC2184-compliant headers in this case.
It looks like probably no other mailer on the planet except maybe Pine
will recognize them, but that's ok, because as you mentioned, the
filename parameter is only advisory anyway, so it's not a big deal if
the recipient can't parse it.
