Ok. My doubts here is to how persistent the RECENT flag is. I want to
have a mail manager open in work and at home, at the same time. If, at a
moment A, a new message notification must be triggered in both clients,
when they check the account for new messages. I may not read this
specific message, but read others. I only want the RECENT flag removed
from it when i _manually_ refresh the inbox (or the folder where it is).
In the other client, though, it does not know of this manual refresh,
so, it will keep the message RECENT until i go there. If i never open
and read the message with one manager, the other will not remove RECENT
flag. This includes other automatic refresh times, that each manager is
configured to use (for my important account, it is every minute).

Does Claws Mail remove the RECENT flag if i do nothing with the manager,
do not read message, and the time to check for more messages come? I
want it to grow the number of RECENT flag messages.

I use UNSEEN messages to control when i want to read them, while knowing
which i have read. So, i want this to be different from the RECENT flag
workings i described above. Is this possible in CM?
