Oh dear, thanks for pointing out this one. No, we don’t use 
improved_mboxlist_sort: 1 yet …

Another question: We use DIGEST-MD5 to authenticate to the mupdate master, too.
What shall I use instead? PLAIN requires TLS, right?
But mupdate doesn't support TLS according to 
https://github.com/cyrusimap/cyrus-imapd/issues/2774
What do you use instead?

Thanks,
Frank
