Mailbox quota DSN code

[Eugene Crosser <crosser@online.ru>]

Matti,

I do not really care too much, but this is what RFC 1893 says:

       X.2.2   Mailbox full
 
          The mailbox is full because the user has exceeded a
          per-mailbox administrative quota or physical capacity.  The
          general semantics implies that the recipient can delete
          messages to make more space available.  This code should be
          used as a persistent transient failure. ^^^^^^^^^^^^^^^^^^^
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
now a bit earlier:

    2.X.X   Success
    4.X.X   Persistent Transient Failure
    5.X.X   Permanent Failure

from this I can conclude that "mailbox full" code is 4.2.2 not 5.2.2.
