No thanks. We've discussed forgeries and message interception many times. They are both, IMNSHO, horrible ideas. As Foundation says, they create distrust in the message system. And since the message system is really the heart of the game, it creates distrust in the game itself. People will get around it by simply asking OOC, or asking the sender "did you *really* send that?" It really won't add anything worthwhile to the game.
You do have a very good point.
If the idea of forgeries is to spread misinformation / bad intel, what about bogus monters/undead/battle reports? (battle reports would be very easy to spot as fake as seeing your name in a battle you didn't participate in will be obvious). However, fake undead/monster reports may cause people to go investigate, which wastes their time. Scout reports could easily disprove the forged monster/undead reports.
