If you are willing to sacrifice usability of your machine for another
five minutes, you can try re-applying that patch, then changing the
following lines in functions/mime.php:
1) comment out line 792 so it looks like:
//case '"':
2) change line 843 so it looks like:
if ($k > 126 || $string{$i} == '"') {
I think this will have the same result, but having a real world test
to help verify would be a big help. It seems that encoding quotes
makes too much use of this code, but the only other fix is to rewrite
the function parseAddress in the Rfc822Header class because it tries
to parse by and then strip out quotes regardless of if they are
embedded in an encoded part of the string.
