small but annoying problem in mail 2.0.5

Recently EVERY single email I have started in Mail has had a pop up box in it about 30 secs after I click "compose". It says the same thing every time, "this message could not be saved," and then I click it away. I know this doesnt seem like a big deal but its really annoying consider it happens for every message I write.

Is there any easy way to stop this?

Which program you use?

I take it that you have tried fixing the permissions and ran the maintenance scripts ?

You could also try trashing the preference file but you may have to set your accounts up again.
