Actually, it's a damn GOOD reason to not include the feature. Users are
notorious for not reading the manual. They also point fingers at us when
they lose mail, doesn't matter if they are the ones to blame or not.
Giving them a gun to shoot themselves in the foot with is a BAD idea.

If you had to work as tech support for any amount of time, you'd quickly
realise that.

This is not the reason it's not included. The reason it's not included
is because users WILL turn it on and users WILL lose mail and users WILL
complain to us and blame us for them losing mail. It WILL happen, and we
don't feel like taking the blame. So if you want to delete duplicate
messages based on Message-Id values, then go ahead an write a filter and
have Evolution run it, or else implement it in your own copy of
Evolution. You have that choice, Evolution is Open Source/Free Software
after all.

If we ever find a fool proof way of deleting duplicates that cannot
possibly be exploited by malicious users, then we will implement it in
Evolution.
