Actually now that you mention it some terminals (GNOME I think?) have a
feature where they'll identify strings with an @ in them as e-mail
addresses and if you click on one they'll try to fire up some GUI mail
client with a new e-mail addressed to that.  This interacts poorly with
using message IDs a lot.
