Correct. > Or the other way round: A server MUST NOT change the \Recent flag for a > single message at any time until a session is closed or a message is > expunged? Correct. By "session", we mean the state from SELECT until a subsequent SELECT, EXAMINE, CLOSE, or LOGIN in that IMAP connection.

Only if the EXPUNGE removed all recent mesages. Note that there's a bit of complexity with EXAMINE. EXAMINE is intended to snoop at a mailbox without leaving any traces (it's not widely used by client as far as I know). The important thing is that EXAMINE does not prevent a subsequent SELECT from seeing messages as \Recent; "it never happened." I would not worry excessively about EXAMINE other than making sure that it doesn't leave any traces. For example, some implementations do not see new mail in an EXAMINE session; you have to SELECT before the new mail appears in the mailbox. -- Mark -- http://staff.washington.edu/mrc Science does not emerge from voting, party politics, or public debate.
