Your regex fails to parse:

"Someone with a comma, and an escape double quote \" in its name"
  <regex.cant.be.used.for.serious.parsing@i.told.you.so>

That's why I first hinted at some MIME library that has probably made
that right.

Not to mention that you don't fix the multiline issue, but that is quite
less of a problem, it merely needs an accumulator and a 1 line lookahead
in the parser code while in the header parts. Nothing unrealistic for me
to write.

But I just can't resolve myself to parse anything with regex because I
just know it's horribly broken and wrong.
