That's correct. LSUB in UW imapd in UW imapd only shows \NoInferiors for
INBOX. It only shows \NoSelect when a % wildcard matches a subscribed
name at a higher level.
Note the following text in RFC 3501, section 6.3.9:
The returned untagged LSUB response MAY contain different mailbox
flags from a LIST untagged response. If this should happen, the
flags in the untagged LIST are considered more authoritative.
A special situation occurs when using LSUB with the % wildcard.
Consider what happens if "foo/bar" (with a hierarchy delimiter of
"/") is subscribed but "foo" is not. A "%" wildcard to LSUB must
return foo, not foo/bar, in the LSUB response, and it MUST be
flagged with the \Noselect attribute.
Many people misunderstand what LSUB does. A name returned by LSUB does
not necessarily even exist! The IMAP subscription facility is best
thought of as being equivalent to bookmarks in a web browser.
