I am aware that standardized e-mail labels, keywords, tags is a mess. But here goes anyway.
mutt comes with https://www.neomutt.org/feature/keywords patch.
My IMAP server is
:set index_format = ... %Y ... works for label names stored directly in relevant headers, but for IMAP, protocol-specific keywords are used for storage (http://wiki2.dovecot.org/MailboxFormat/Maildir) and these are not showing up.
mutt doesn't seem to be able to get to them, even with the
feature/keywords patch. Am I misconfiguring or missing something?
