I turned idled back on this morning as the user says she is still missing
emails. This particular user has hundreds of folders and hundreds of
sieve rules to automatically file messages into these folders (co-worker
messages go into co-worker folders and she wants to be notified (unread
count) that there's a message in a co-worker's folder, etc.). Is there
a setting on sieve I need to tune?
