An issue I've had with QUOTA in the past is that I've set a limit on storage but not on "number of messages". Internally, our server is storing all the counts, but it has "-1" (aka: unlimited) as the limit.

There's no way in the wire protocol to indicate this. I'm not sure if it's possible to do it in a backwards compatible way other than just say "use UINT32_MAX for unlimited", but it would be nice to define that in the spec and tell clients to treat UINT32_MAX in that field as "unlimited" for display purposes.

Cheers,

Bron.
