yes, this is wallace (grr...) Have a look on the thread "wallace breaks
dkim signature" from two weeks ago.

The solution could be to send all mails as quoted-printable. But:
should't a gpg signed email always be sent as quoted-printable? On my
enigmail at least every signed mail is sent as quoted-printable - even
if the same mail would be sent in 8bit if it's not signed.

So for me it looks more as a client problem
