Good day,I am currently testing Sophos Central Email Advanced.I want to allow users to do the following:1. If S/MIME is available - to encrypt messages fully automatically via S/MIME.2. If S/MIME is not available - to send unencrypted messages.3. If the user absolutely wants to encrypt, whether with or without S/MIME: always encrypt the e-mail using a defined subject line tag.I'm currently noticing that the subject line tag doesn't work as soon as S/MIME is turned on.What do I have to change?Many thanks for your help.
