a APPEND INBOX CATENATE (TEXT {0}
)

This isn't explicitly prevented by the RFC. So I guess it means that the TEXT {0} parts can be simply skipped.

Regardless of the above, it's possible to also create empty URL streams (e.g. a partial starting from offset 100000000). Should it be allowed to save empty messages?.. I'm thinking I'll just return NO to such APPENDs, although with MULTIAPPEND that's a bit bad behavior to abort the whole APPEND.
