I think "useless" is quite an overstatement and I'm not sure Benny is 
right about correct implementations. However, it is mostly useful for 
simple clients and accounts that don't have multiple clients accessing 
them.

In the context of an IMAP session, \Recent means that no other 
read/write IMAP session (i.e. one initiated with SELECT) has been 
notified of the existence of the message. Clients cannot change this 
flag. It is useful for IMAP clients to identify "new" messages in a 
mailbox that may merit special treatment (e.g. apply filtering rules) 
but arguably it is pointless and misleading to expose \Recent to the 
user of a complex IMAP client like MM.
