Has anyone tried to subscribe to the roundcube list by sending a blank email from within Roundcube? I tried several times with different addresses. Roundcube does NOT allow this, so I was unable to subscribe to this list from roundcube.

You can put whatever you like in the subject and body when subscribing to the RoundCube lists. The important bit is to send it to the correct address...
