There should be a way a decker can create a daemon to track a specific Grid Mail account, maybe for a MUCH shorter duration than normal daemons, which tracks in-bound and out-bound grid mails and views some of it's content. Of course there should be counter measures, like ICE being installed somewhere to prevent it from being viewed, and/or defensive daemons, etc. And maybe depending on the deckers skill in Cracking, some of the letters in some of the words will be replaced with a random other character like an asterisk, pound sign, etc.
