[Mailman-Developers] Disallowed characters in email address?

Just stumbled across this in Utils.py:

# TBD: what other characters should be disallowed? _badchars = re.compile('[][()<>|;^,/]')

and thought I'd suggest that " and ' get added to that list...

I recently wound up with a list subscriber of the form "foo@bar.baz" (*with* the quotes!) and had a more difficult time fixing it than you might expect.
