Implementing this at the mail system level is one thing, where the mail messages aren't likely to be changed once they're in the mailbox (although they could be deleted). Implementing this at the general-purpose filesystem level is quite another. Besides, unless you're implementing Maildir or something like that, even if this was implemented at the filesystem level, it wouldn't help you with duplicate copies of a message in multiple mailboxes, since the rest of the contents of the mailboxes are not likely to be identical. -- These are my opinions and should not be taken as official Skynet policy ========================================================================= Brad Knowles, <blk@skynet.be> Sys.
