Unexpected result from LIST EXTENDED command

Tue Jul 16 11:41:06 EEST 2019

There is no error in the server logs. I checked those particular folders on the server and they don’t seems to have anything special about them, like permission or etc.

Yes, calling STATUS on those particular folders returns the status. The folders can be opened and they have emails in them so nothing special about those folders.

I am executing this command below to dovecot-2.3.5-6.cp1178.x86_64 server

Notice that some status responses are missing (For folders INBOX.Archive, INBOX.spam.&-BD0EOQQ9BDkEPQ-). I wonder If this is a bug or working as expected

In rfc5819 there is this:

If the server runs into unexpected problems while trying to look up
the STATUS information, it MAY drop the corresponding STATUS reply.
In such a situation, the LIST command would still return a tagged OK
reply.

May be that is the reason for this response? Is it possible to find more details in server logs why STATUS is missing?

Do you see any errors logged? Does it work if you ask with STATUS command directly those folders? What's your doveconf -n?
