One of my users was recently complaining that all the mail he received that
was PGP signed had broken signatures. While investigating, he determined
that the MIME headers of the messages were being altered by our gateway
resulting in broken signatures.
Headers on the original message look like this:
--Qxx1br4bt0+wmkIi
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Content-Transfer-Encoding: quoted-printable
After passing through our gateway, they look like this:
--Qxx1br4bt0+wmkIi
Content-Type: text/plain;
charset="us-ascii"
Content-Disposition: inline
Content-Transfer-Encoding: quoted-printable
The Content-Type header has been broken into two lines, and quotes have
been added around the charset.
Is amavisd altering the messages in transit? We use postfix as our MTA, if
not amavisd then it must be doing it? Any suggestions as to the culprit or
a resolution would be much appreciated...
Thanks...
