S/MIME singing only works if mailbody is empty or has just one word #9796

Open cypress-hill-car opened 3 months ago

cypress-hill-car commented 3 months ago

Steps to reproduce

  1. install a S/MIME Certificate
  2. add Cert to the Mail-Account
  3. Send a Mail "S/MIME signed" with no Text in the body => Works fine
  4. Send a Mail "S/MIME signed" with Text in the body => Singing invalid (view Sent-Folder)

See test results of "Test Signing 1" with empty mail body and "Test Signign 2" with filled mail body: signed_none_empty_mailbody signed_empty_mailbody

Expected behavior

Mails with Attachments and/or Text in Mailbody should be signed properly.

Actual behavior

For signed emails with attachments and/or text in the mail body, the signature verification fails.
