There doesn't appear to be a way to toggle auto-decrypting messages in OS X Mail. With the EFAIL vulnerability announced today, [1] this would be a good way to mitigate the vulnerability.

Thanks for your attention and continued work on a great open-source product!

Expected
A checkbox in the GPGMail pane of Mail preferences with the option of decrypting emails.

macOS                   10.12.6     16G1314
GPG Suite               2018.1      2083    (9658b70)
GPGMail                 2.7.1       1254    (7d871d1)
GPG Keychain            1.4.2       1403    (128637e)
GPGServices             1.11.2      969     (e5438f7)
MacGPG                  2.2.3       900     (cead4f9)

   Hi Adam,

   it is true that at the moment it‘s not possible to disable automated decryption of encrypted messages. That would however not necessarily help in this case.
   What does help, is to disable the loading of remote content in Mail preferences.
   For more details, see https://gpgtools.org

   Since this feature request has come up in the past though, we will add your voice to that request!

   Thanks, Luke, will do!

   I guess I misunderstood the decrypting option. I suppose the safest bet would be to remove GPGMail altogether, but retain other parts of the suite. I've done this in the past when there were compatibility problems with Mail.

   Hi all,

   excuse the late reply - the last weeks were very busy with the release of GPG Suite 2018.2 and 2018.3.

   2018.2 brought the efail fixes to macOS High Sierra and 2018.3 includes the backport of those fixes to macOS Sierra.

   Best,
   steve
