[issue11700] mailbox.py proxy updates

[Amaury Forgeot d'Arc]

Amaury Forgeot d'Arc <amauryfa at gmail.com> added the comment:

mbf.close() should not fail when called twice. The close() method in the io module states that "This method has no effect if the file is already closed."
But then, is "close=False" necessary?
