Security.plist signing settings no longer working

First, try launching from a Terminal window to see if you get any error messages:

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

Also try that after enabling:

defaults write com.freron.MailMate MmDebugDerivedSecurity -bool YES

You are welcome to send me output using “Help > Send Feedback”.

Running MailMate from the terminal yielded the following. The compose window first opened with a from address not configured for signing. I switched it to one which is configured for signing, yet the sign checkbox remained unselected.

Warning: Decoding empty text body for id 245026
Warning: Decoding empty text body for id 245026

Adding MmDebugDerivedSecurity yielded this (email addresses obscured) when doing the same sequence as above:

Deriving security for new message
From address: 'email3@gmail.com'
Security: none
Protocol: OpenPGP
Warning: Decoding empty text body for id 245030
Deriving security for message 245030
From address: 'email1@domain1.com'
Security: none
Protocol: OpenPGP

"email3@gmail.com" is listed under signingDisabledPattern in my Security.plist file, while "email1@domain1.com" is under signingEnabledPattern.

Hope this helps.
