The "FUZZY" algorithm was therefore renamed to "text/imap-fetch-preview" so that the semantics could be identified using the new media type method. > > As part of this, it was necessary to clarify that the default algorithm, if either no algorithm list was provided or no algorithm was associated with a LAZY modifier, MUST be text/imap-fetch-preview. Now that there is not a way for a client to determine which algorithms a server supports ("PREVIEW=" capability detection was removed), this seems to be the only rational choice - allowing every server to potentially specify a different default algorithm would lead to an inconsistent IMAP experience across installations. > > I think this covers everything that was discussed at the last meeting. This is a move in the right direction, but we are not quite there yet. I have a few questions that might affect my specific suggestions: 1) The document says to use media type syntax, but not necessarily media types. If you want the former, you probably need a new registry (I recommend against that). If you want the latter, then why not just use text/plain, as a registered media type? 2) If there is a good reason not to use "text/plain", you need to registered "text/imap-fetch-preview" with IANA. 3) For unsupported media types, it would be good to define a new IMAP response code, similar to BADCHARSET.
