Google "IANA registry IMAP capabilities" (without the quotes). First hit is what you want; follow each RFC reference for more details. Capabilities which begin with "X" are non-standard, and you'll have to search for them separately. For a general description of the CAPABILITY syntax see RFC3501 (sec 6.1.1 and 7.2.1) HTH, Brian.
