The following errata report has been rejected for RFC6154,
"IMAP LIST Extension for Special-Use Mailboxes".

You may review the report below and at:

Status: Rejected
Type: Editorial

Reported by: Bron Gondwana <brong@fastmailteam.com>;
Date Reported: 2018-07-19
Rejected by: Alexey Melnikov (IESG)

Section: 2

Original Text
An IMAP server that supports this extension MAY include any or all of
the following attributes in responses to the non-extended IMAP LIST

Corrected Text
An IMAP server that supports this extension SHOULD include any or all of
the following attributes in responses to the non-extended IMAP LIST

There exist clients which send a non-extended LIST command and will correctly display and interact with mailboxes usefully if their special-uses are given in the response.

Because of this, many servers are already replying with the special-use attributes, and there are no known reports of clients being broken by that behaviour.  Because of this, the MAY should be raised to a SHOULD, and server implementations should default to turning this on.
The right way to make this change is to revise the document. MAY was intended at the time of publication.
