Since a client can't assume that STATUS is lightweight -- and in fact the IMAP specification explicitly permits STATUS to be non-lightweight -- it is also a bad idea to do ongoing polling with a STATUS command. Therefore, by elimination, a client which wishes to monitor some modest number of mailboxes is best off doing so via static IMAP sessions in IDLE or NOOP polling state. The best solution for monitoring multiple mailboxes is by some sort of MDA-triggered notification and not by polling via IMAP at all. -- Mark -- http://staff.washington.edu/mrc Science does not emerge from voting, party politics, or public debate.
