  Based on the output, it seems like it's hanging. You can try enabling debug output like this (in the Terminal):

  defaults write com.freron.MailMate MmDebugSecurity -bool YES
  

  And then launch MailMate like this:

  /Applications/MailMate.app/Contents/MacOS/MailMate
  

  Part of the output is the gpg2 command used and its arguments. You can try that manually and see if that works.

  Thanks in advance.

  Apparently, it's the strength of my key that doesn't work with the command line option of "--digest-algo SHA1" Changing it from "--digest-algo SHA1" to "--digest-algo SHA256" works.

  • State changed from “new” to “accepted”

  Ah, I think this is actually a known issue which I haven't fixed yet. A workaround is available with the following setting:

  defaults write com.freron.MailMate MmOpenPGPHashFunction -string sha256
  

  This is not a permanent solution, but it might work for you for now. (Restart MailMate.)

  I am encountering the same error and have taken the steps suggested above.

  MM's signing dialog looks like:

  USERID_HINT NEED_PASSPHRASE 2515EAB55D06505D 2515EAB55D06505D 17 0 GOOD_PASSPHRASE BEGIN_SIGNING H2

  The console lists this:

  2015-01-20 10:54:49.591 MailMate[63122:10568022] Warning: Unknown security problem (OpenPGP): unknown

  Not particularly detailed.

  I am using MM build 5035 and the newest GPG Suite (Beta 4 for Yosemite).
  Thanks,
  John

  I was having this problem as well and it SEEMED like the preference change didn't take, because even after the change when I tried again to re-send the failed test message from the Drafts folder, the debug output showed:

  OpenPGP
  gpg2 --no-verbose --batch --no-tty --openpgp --status-fd 2 --digest-algo SHA1 --textmode --armor --detach-sign --local-user "bill@scconsult.com"

  This appears to be because MM is saving drafts which were set to be signed when they were saved with this header:

  Content-Type: multipart/signed;
  boundary="=_MailMate_432EC9DA-1963-489E-BD0A-1D3F06BFD353_="; micalg=pgp-sha1; protocol="application/pgp-signature"

  The workaround for this is to open the draft that couldn't be signed before the setting change, unset the signature toggle, save it, then re-open it and turn signing back on.
