GPG Mail: Can't use S/MIME signature if both S/MIME and GPG are installed

If a S/MIME certificate and GPG Tools are installed, selecting S/MIME from the new mail selector does not allow to send a S/MIME signed email, but the message will be signed with the GPG key.

If S/MIME is selected on the top-right corner and and the sign button is activated, a S/MIME signed email message should be sent.

    Hi Mario,

    welcome to the GPGTools support platform. Sorry you are having problems using GPG Suite.

    We have a ticket for this problem. I connected this discussion with the existing ticket. That means, should this discussion get closed, it will be re-opened as soon as the ticket is closed. That way you'll stay in the loop and get notified as soon as we have news. Feel free to open a new discussions should you run into further problems or need assistance.

    The problem is, that currently in GPG Mail on macOS Catalina, that switching away from the default method is not repected. That means whichever method you set as default it will always be used. Switching via the top right indicator will not be repected. So the workaround currently is to switch the default. Obviously that is not very convenient and we will try to resolve this problem soon.

    This KB-article explains how to adjust the default method.

    Sorry for the inconvenience.

    All the best,

    Hi Mario,

    the issue where GPG Mail was not respecting, when the method was switched via the top right indicator in a mail draft, has been fixed. If you want to test the fix, please download our latest hotfix GPG Suite. That page also has Signature file and SHA256 to verify the download. Thanks for helping us test this fix.

    Should the problem persist, please do let us know.

    Should you see trouble using GPG Suite in the future, don't hesitate to get in touch and open a new discussion any time.


    Disclaimer: This is a development version which has not been thoroughly tested yet, so bugs or crashes are to be expected.
