Are you sure about that?  Apart from explicitly changing the flags using 
the IMAP STORE command, a message only gets the \Seen flag if it is 
FETCH'ed by an IMAP client.  However, I'm attempting to change the flags 
before it even hits the inbox.

What I'm actually trying to do is save the message to a folder but mark it 
as seen, and then deliver it to the inbox as unseen:

     require ["fileinto", "imap4flags"];

     addflag "\\Seen";
     fileinto "archive";
     removeflag "\\Seen";
     keep;

The archive folder works as expected (the \Seen flag is set), but the 
inbox also has the \Seen flag set, which is what I don't want.
