I have a slight problem wherein every time I start up a game of NetHack, I completely lose touch with my surroundings for hours on end. Thankfully The DevTeam Thinks Of Everything and there’s a solution that allows communication with the outside world without breaking immersion: the mail daemon! If compiled with -DMAIL and OPTIONS=mail is set in your runtime configuration (the default on Linux), NetHack will periodically check a user specified mbox file (MAIL) for new mail, and upon receiving an email a mail daemon will spawn in and deliver a scroll of mail to the player.
