Gilles Lenfant just reported a bug in quopri, in that it quotes a
single '=' as '==', which is incorrect. Could that be the cause of the
problem?

You can turn-off the autoconversion if you want. Since sendmail is
generally using autoconversion only on a 8-bit-clean channel, and
since autoconversion is generally guaranteed to not lose any
information, the autoconversion itself should not be a problem.
It is more likely that the data you send was not quoted-printable.
