That behavior (empty permanentflags but flags) is explicitly allowed. And if you read the spec VERY carefully you'll find it's REQUIRED if the user can't modify the folder. The server maintains flags, but they aren't persisted.
Think of it this way: FLAGS is the set of flags supported by the server. PERMENANTFLAGS is the set of flags that will be persisted in the server's database. FLAGS is necessarily a superset of PERMENANTFLAGS, but they are different and have different meanings.

We're responsible for 'SnapperMail' (www.snappermail.com) a wireless email client for PalmOS based devices. Question: How well honoured are FLAGS vs PERMANENTFLAGS in the IMAP community? Is PERMANENTFLAGS overdesign that actually isn't used in the wild that often? Do other clients actually only honour FLAGS and disregard PERMANENTFLAGS? Is ask beause our IMAP client is currently coded closely to RFC3501 in this respect however we've received a number of reports from users of servers that persistently return empty (i.e. "PERMANENTFLAGS ()") responses while still allowing the flags in FLAGS to be permanently set on messages in the mailbox. This seems in direct violation to the RFC however other IMAP clients happily set flags on these particular servers. Is it worth just relaxing our client on this point hence disregarding PERMANENTFLAGS and simply relying on FLAGS and the READ-WRITE/READ-ONLY folder property?
