Thank you. I noticed this while gooling around about Box Trapper.

3 Remote Commands
ASK checks the ``Subject'' line of incoming mails, looking for special strings called ``Remote Commands''. By sending emails to your own account using these strings, it is possible to manage the queue, edit the lists and others.
ASK understand two flavors of remote commands: HTML mode and Text Mode. You can select the desired mode by locating editing your .askrc file and changing the rc_remote_cmd_htmlmail parameter to ``on'' or ``off''. HTML mode requires an HTML capable mail reader. Text Mode can be used with any mail reader.
To find out about the available remote commands, send yourself a message with ``ASK HELP'' in the subject. ASK will reply with the list of commands.
