I can't speak to _all_ mail systems, but the Maildir format doesn't have any indexes inherent in it. Most IMAP clients create their own indexes for speed purposes. I know Dovecot is smart enough to notice if an index is out of date or corrupt and rebuild it as needed. Courier has special commands to rebuild indexes as required. Anything that doesn't fit into one of these categories isn't worth using IMHO. -- Bill Moran Collaborative Fusion Inc. **************************************************************** IMPORTANT: This message contains confidential information and is intended only for the individual named.
