Chatting with Florian off list it seems likely that the Postfix
smarthost
is accepting Content-Transfer-Encoding: 8bit messages, DKIM signing
them,
only then discovering that the recipient MX doesn’t offer 8BITMIME.
It
rewrites the body using quoted-printable encoding, breaking the
signature
in the process.
So this is probably a good moment to ask on Postfix mailing list what
might
cause this behavior and how this can be fixed.
It seems to me that Steve explained the mechanism perfectly and (in
unquoted text) provided the solution: force_mime_input_conversion=yes
The force_mime_input_conversion switch is relatively new. Available in
3.9+. I believe it was implemented in reaction to a discussion on the
Postfix-Users mailing list last year.
