[Dovecot] Deliver a message marked as read.

Hi.

Is there a way to deliver a message already marked as read.

I would like to configure my MTA to deliver a copy of all sent messages to a folder named Sent in the user Maildir, I believe that it would be interesting to keep this folder always marked as readed.

I'm not sure what define a message readed (a mark, a xheader or something) thats why I'm asking here!

Any idea is apreciated.

Thanks,

Catunda.
