VIS_EMAIL <new email address for the player list>
Set a different email address to appear in the player list than the one the turn reports are sent to.
For example:
email "skrenta@shadow.com" vis_email "skrenta@pbm.com"
Would cause turn reports to be sent to skrenta@shadow.com, while the player list shows skrenta@pbm.com as player 501's email address:
501 House of Osswid Rich Skrenta <skrenta@pbm.com>
