3. Working Group Status Drafts approved: –Vacation, Variables, Relational update, Spamtest update, IMAPFlags, Sub-address update These are in the RFC Editor Queue blocked on 3028bis In IESG evaluation: –draft-ietf-sieve-3028bis-12 (blocked in Cullen's DISCUSS) –Body (IETF LC Completed) In WGLC/WGLC completed: –draft-ietf-sieve-notify-xmpp –Editheader (interaction with mail loop prevention, otherwise ready for IESG) –Notify extension (ready for IESG, Cyrus to do write-up) –Mailto Notification method (another WGLC?) Others: –Refuse/Reject – no update (will be discussed later) –MIME Loops – 03 is out, ready for WGLC?

4. 3028bis Current: draft-ietf-sieve-3028bis-12.txt IETF LC completed During IESG review Cullen raised DISCUSS on mail loop prevention

5. Editheader Philip posted draft-ietf-sieve-editheader-09.txt Addresses most of the remaining issues (.e.g. mail loop handling) Philip will publish a new revision that –adds text saying that editheader can chose to ignore modifications due to policy reasons –In Security Considerations: add text saying that addition of Received are allowed, but deletions of Received will be ignored

6. Notification Draft Current drafts: –draft-ietf-sieve-notify-08 Changes since -07: Added a new "set" modifier for URL percent-encoding Clarified that notification methods must address notification loops Added an implementation consideration for implementations that use URIs internally. -08 addresses all known issues. Cyrus will be sending it to IESG.

7. Reject/Refuse Work has stalled for a while Aaron Stone has volunteered to co-edit the document and move things forward. Aaron will do the following changes as per consensus at the IETF 67: –Revert back to two actions (reject and ereject) –Add more details on how MDNs and DSNs should be generated.

8. Date-time Ready for Last Call

10. Accessing IMAP per-mailbox annotations from Sieve (Overview) Currently draft-melnikov-sieve-imapext-metadata-01.txt (no update since Prague) –Provides ability to read per-mailbox annotations - metadata test –Allows to test for annotation existence - metadata_exists test –Allows to test for mailbox existence - mailbox_exists test –Allows to explicitly create mailboxes on delivery - ":create" argument to fileinto action

11. Accessing IMAP per-mailbox annotations from Sieve (Example) require ["vacation", "mboxmetadata"]; if metadata :is :private "INBOX" "/vendor/isode/vacation" "1" { vacation :handle "holidays" text: I'm on holidays and will reply to your mail upon return.. ; }

12. Accessing IMAP per-mailbox annotations from Sieve (Open Issues/ToDo) Update examples to match the latest Notify draft Do we need a test for server annotations? –Probably yes Add support for LIST-EXTENDED options? ACL :-)? –Possibly as another extension

13. Externally stored lists (Overview) Originated from a discussion with Alexandros Vellis. Currently draft-melnikov-sieve-external- lists-01.txt Why? –Want to have externally stored whitelists/ blacklists/ greylists. E.g. Simon Josefsson suggested DNS blacklists –Want to implement personal mailing lists –Don't want to change the script every time list membership changes

14. Externally stored lists (Overview) How? –Extend the header & envelope tests to accept a new tagged argument :list, which changes the last parameter into one or more names of lists of users –Extend the redirect action with a new tagged argument :list that changes the last parameter to be a name of a list of users

15. Externally stored lists (Example) # Submission from list members is sent to all members if allof ( envelope :detail :list "to" "mylist", header :contains :list "from" "mylist" ) { redirect :list "mylist"; }

16. Externally stored lists (Changes since Prague) Allow for absolute URLs as well as opaque identifiers Added some text describing why relative URLs are disallowed (e.g. LDAP) Added security considerations: mailbombs, DoS attacks

17. Externally stored lists (Open Issues/ToDo) Need to specify exact ABNF for the list identifier –Dave Cridland suggested to use “:” prefix for “opaque identifiers” Add more security considerations: handling outages in the service that provides information about an external list

18. Milestones - overdue Again! Proposed an update, but already missed some of its milestones
