OMA MEM liaison• Response to specific questions
– will study the possibility of a shorter list that is mandatory for the MEM enabler for OMA STI. We will provide IETF LEMONADE an update on this after our next meeting.
– only notification and send/receive roundtrip delay is of concern at this point.
– message recall is still a requirement. Specifically, that the client be able to request a recall and that success/failure be indicated back. MWG-MEM will let IETF know if any further work is requested.

Compression
• Application Level versus Transport Level– Beijing:
Application = MUST, Transport = MAY– draft-ietf-lemonade-compress
• Do We Reopen This?– Data Showing Both Good and Bad
• Only Looking at Size, Not CPU– One More Complex Than Other– Do We Need an Indicator, for Either, for On/Off?– How Can Client Possibly Know If Compression Is
Valuable?

March 20 and 22, 2006 IETF 65 - Dallas, TX, USA 20
Proposed Mandatory list of Conversions to support for draft-ietf-lemonade-convert-xx• Proposal from Alexey / Chris / Stephane• HTML to Text:
– Details to be worked out from STI doc etc…• HTML, XHTML, …• Doc structure• Tables…
• Images: – image/gif, image/jpeg and image/png
(un- / no more encumbered)– Parameters from STI:
• Size limit (i.e. reduce quality), • width, • height, • resize directive (crop, stretch, aspect ratio)• Note: we have not considered depth, is this needed?
March 20 and 22, 2006 IETF 65 - Dallas, TX, USA 21
Proposed Mandatory list of Conversions to support for draft-ietf-lemonade-convert-xxContinued:• 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, 2006 IETF 65 - Dallas, TX, USA 22
Additional thoughts for CONVERT
Not part of the proposal from task force (two previous slides)
• Add a compression transformation for object level compression based on discussions of Monday
• Will take to the list

Reconnect Status
• Got New draft-05– Did Not Last Call (Next Slide)– After Meeting
• Depends on– CONDSTORE, expunged,…
• Need implementations of 05
March 20 and 22, 2006 IETF 65 - Dallas, TX, USA 25
Reconnect Issues
• What state is to be saved by the server?• Address some edge cases, e.g. "SID, SID <session-
id>, 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, 2006 IETF 65 - Dallas, TX, USA 26
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, 2006 IETF 65 - Dallas, TX, USA 27
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
March 20 and 22, 2006 IETF 65 - Dallas, TX, USA 28
Encryption
