as I understood RFC 2822 3.4 the From header should contain the '<' and
'>' as described in the 'angle-addr' spec. There are some exceptions but
this is the default. The domain and user parts of the address however
must consist of 'quoted-string' which is US-ASCII without some special
chars. Therefore patchwork is false here due to wrongly coding the address.

I had some time to dive into this and found the root cause of the
re-coded From header.

Patchwork recodes the 'From' header of the mail in the Patch model. The
following snippet might fix it, unfortunately I have no clue how to
verify it really works without installing the whole thing:

Maybe the Person model should be expanded by some method to provide a
correctly formatted Header() for the 'From' field?
