Not compatible with Sonoma Mail digital signature and encryption feature, which I use with the apporpriate certificates.

When viewing signed emails, the Signed label isn't displayed with the MailTrackerBlocker message security extension. Also the signing/encryption icons are greyed out in the message composer. Tested with Actalis' free S/MIME cert.

Implemented the "Signed" indicator when viewing messages in 1.1.6.

Composing emails with signing and/or encryption is yet to be implemented. For now, you'll need to disable the MailTrackerBlocker extension if you need to send signed or encrypted emails.
