RFC Errata
RFC 6154, "IMAP LIST Extension for Special-Use Mailboxes", March 2011
Source of RFC: morg (app)
Errata ID: 5581
Status: Reported
Type: Technical
Publication Format(s) : TEXT
Reported By: Not clear whether SPECIAL-USE implies LIST-EXTENDED
Date Reported: 2018-12-21
Section 5.2 says:
C: t1 CAPABILITY S: * CAPABILITY IMAP4rev1 SPECIAL-USE S: t1 OK done
It should say:
C: t1 CAPABILITY S: * CAPABILITY IMAP4rev1 SPECIAL-USE LIST-EXTENDED S: t1 OK done
Notes:
Is it okay for a server to support SPECIAL-USE without supporting LIST-EXTENDED? The example seems to imply this, but it's not clear from the RFC text. Section 2 starts with: "For the extended list command [RFC5258]", but doesn't say the server MUST support LIST-EXTENDED.
