             Summary: Strengthen Mailbox name validation upon mailbox creation
                 Key: MAILBOX-392
                 URL: https://issues.apache.org/jira/browse/MAILBOX-392
             Project: James Mailbox
          Issue Type: Improvement
          Components: api
            Reporter: Benoit Tellier


https://tools.ietf.org/html/rfc3501#section-5.1 states that:

{code:java}
   3)    Although the list-wildcard characters ("%" and "*") are valid
         in a mailbox name, it is difficult to use such mailbox names
         with the LIST and LSUB commands due to the conflict with
         wildcard interpretation.


   5)    Two characters, "#" and "&", have meanings by convention, and
         should be avoided except when used in that convention.
{code}

However there requirements are not enforced by the mailbox backend.

With JMAP we can create a mailbox containing forbidden characters leading to invalid mailbox namesfor instace containing `#`
