          Issue Type: Improvement
          Components: IMAPServer
    Affects Versions: 3.4.0
            Reporter: Benoit Tellier


We encountered the following exception within one of our production environment:


{code:java}

Apparently the issue is caused by a "NEEDED_DATA netty channel attachment not having been well positioned.

Super class method can be called in this case to be more resilient.
