IMAP Flags clarification.

[Joseph Brennan]

\Seen is an IMAP flag. Unseen means "Messages that do not have the \Seen 
flag set."

I don't know what "high priority" means in this context. If you mean 
headers like "Priority: Urgent" or "X-Priority: 1", those are not IMAP 
flags. And for that reason I don't know what Michael Slusarz means by the 
order in which the server returns the flags.

Evidently Horde IMP can show only one of the two things, but whether it 
prefers an IMAP state to the content of a header sure seems to me like an 
IMP client-side decision.

I am probably missing something here.
