March 20 and 22, 2006IETF 65 - Dallas, TX, USA21 Proposed Mandatory list of Conversions to support for draft-ietf-lemonade-convert-xx Continued: Audio: –Not considered because of lack of widely used unencumbered codecs –To be treated as others Others: (including, proprietary document formats, audio, video, …) –To be described via MIME types and STI parameters –May not be supported by server => behavior described in draft Should be validated with device manufacturers and operators

March 20 and 22, 2006IETF 65 - Dallas, TX, USA25 Reconnect Issues What state is to be saved by the server? Address some edge cases, e.g. "SID, SID, SID". Is the last operation "create new session", or should it be noop? Figure out if RECONNECT should depend on EXPUNGED extension (extension to send a compressed list of expunged messages). Is LOGOUT (PRESERVE) needed? Do we need to add a new DELETESID command (i.e. a command to delete an existing session without logging out)?

March 20 and 22, 2006IETF 65 - Dallas, TX, USA26 RFC2192bis – IMAPURL Status Updated text on mailbox naming scope field (section 3.1), more changes to this section needed. Updated section 3.2 to describe anonymous logins and client behaviour if it sees LOGINDISABLED IMAP capability. Reworked section 5 (listing IMAP server content) to talk about NAMESPACE command. Removed references to Content-Base header, as it was obsoleted. Updated reference for Content-Location header to point to MHTML Allow for UTF-8 (as non-synchronizing literals) in Search criteria Clarified that IMAP usernames and Search criteria can contain UTF-8 data. Fixed error in ABNF for partial body range. Added IANA considerations section (more work is needed). Updated references

March 20 and 22, 2006IETF 65 - Dallas, TX, USA27 RFC2192bis Issues Include URLAUTH IMAP URL extension into this draft? Extend syntax to allow for BINARY, SEARCH return options (ESEARCH extensions), LIST- EXTENDED, etc.? (I think the answer to this question is yes, the question if we want to put all mentioned IMAP URL extensions in 2192bis) ABNF Error Will Be Fixed in Next Version
