A socket. You can write a daemon that starts up when you boot the
machine and get it to prompt you (the console) for the password. It can
keep the password in main memory (though of course this could get
written to swap disk; you'll have to think about that). Exim can read
the password using ${readsocket. Alternatively, you could use a named
pipe.
