For security, a salt should be appended to the tag name to make dictionary attacks on the tags more difficult. For their owners' convenience, mail clients will want a mapping of hash to tag name. > [...] pseudo-mails stored in Maildir and synchronised by IMAP A single RFC2822 message can store the salt and hash-to-tag database. It could contain a clear subject and directions to the end user not to move or delete it. This would not, I think, terribly confuse existing mail clients or their users. -Dave -- David A.
