Right - using Thunderbird at work as an imap client gives
the new mail 'beep' when I transfer an unread mail from
one folder back to the Inbox: obviously a false notification for the very reasons you express.


So the best we can do is limit the cases of false notifications. We can clearly do alot better than the current situation in Evolution.

My patch suggestion, once suitably tidied, should limit
false notifications to when a message is moved to a folder
that (then) contains unread messages.

I wonder if we could easily go further, by
a) seeing if the messages just added to the folder all have
unread status
b) limiting the notifications to only be issued if the
folder affected is an appropriate folder for brand new
mail (i.e. an 'Inbox' type folder).

Not sure how easy either of the above are, but they would
help limit the problem as much as we can.
