Hi, Just as an aside we archive our root mail (lots of crap) into a cyrus mailbox and found that past 250k messages it just began to suck at the client layer. What we did was have sieve filter that would be re-generated on a monthly basis (using sievec) in the account that would filter into a folder for that month. The only thing was that you would have to pre-populate the folders (or maybe I am a sieve noob and not aware of a way that sieve can create the folder if it doesn't exist). Anyway this is a pretty good way to deal with large archival mailboxes. Thanks, derek -- --- Derek T.
