What do you mean "downloaded again" - how do you see it? Are you talking about IMAP or POP3 protocol? A missing IMAP flag doesn't cause redownloading, it would at most cause the mail to not be displayed as forwarded/junk. It sounds like something else is going wrong (the mail getting a new UID for some reason?)
