Show info when gpgol is in conflict with ol
* src/mail.cpp (Mail::prepareCrypto_o): Check the Outlook crypto flags and show warning. * src/mail.h: Update accordingly. * src/mailitem-events.cpp (SEND): Abort when prepareCrypto_o returns a value.
This improves the case where GpgOL has S/MIME disabled
but outlooks internal S/MIME is used. In that
case we would previously have undefined behavior, now
we either abort the operation or overwrite outlooks
This helps but does not solve:
