[Mauro De Gennaro <[e-mail]>]

Hi Ken,

That would be nice, thanks. I think 5 minutes to present the draft and 5 minutes to discuss should be enough?

Best,

Mauro

Hi Mauro,

Would you like some time during MAILMAINT to introduce this draft as a possible work item?

I’ve just submitted the OBJECTID Account Identifier Internet Draft to Datatracker, which proposes extending the IMAP OBJECTID extension to support account identifiers.

As this is my first time submitting an I-D, I’m not entirely sure what the next steps are beyond sharing here for discussion in the WG. I would appreciate any guidance and, of course, any feedback on the draft itself is very welcome.

Below are the details:

Name:     draft-degennaro-imap-objectid-accountid

Revision: 00

Title:    IMAP OBJECTID Account Identifier extension

Abstract:

  This document extends the IMAP OBJECTID extension (RFC 8474) to

  support account identifiers, enabling IMAP servers to provide

  account-level context for mailboxes when multiple accounts are

  accessible through a single IMAP connection.  This extension is

  particularly relevant for environments where IMAP mailboxes include

  shared mailboxes from multiple JMAP accounts, as defined in the JSON

  Meta Application Protocol (JMAP).  By introducing the ACCOUNTID

  object identifier, this specification ensures that mailboxes can be

  uniquely identified across different accounts in both IMAP and JMAP

  contexts, thereby facilitating seamless interoperability between the

  two protocols in multi-account scenarios.

Thanks,

Mauro

Hi all,

I unfortunately missed the submission deadline for a new draft I’ve been working on, which defines an extension to IMAP adding account-level object identifiers to complement the existing OBJECTID framework.

I’ll upload the draft as soon as submissions reopen on November 1st, but in the meantime it’s available online at https://rfc.stalw.art/imap-objectid-accountid/" class="moz-txt-link-freetext" rel="nofollow">https://rfc.stalw.art/imap-objectid-accountid/

If there’s time on the Montreal agenda, it would be great to give it a quick look; otherwise, we can continue the discussion here on the list.

Best,

Mauro
