Summary: 2.0.8 borks on dot in local part of addr

Initial Comment:
In a mail address's local part (the part to the left of
the at sign), it is perfectly valid to have periods. 
However, mailman stops reading the address right at the
@, so that "mr.bad@pigdog.org" is shown as "mr.bad". 
this is disastrous for lists where only subscribers are
allowed to post, since the system doesn't allow for
exceptions that lack an @ and a FQDN.

Either allowing exceptions to be of a more forgiving
format, or fixing the broken regex that truncates the
mail addresses would solve my problem.  I'm getting
tired of moderating a legitimate user's posts,
especially since the system won't even send the
warnings to the correct address.

This happens even when I use python 2.2

This is really a bug with earlier versions of Python, I
believe.  MM2.0.x uses the standard library function
rfc822.parseaddr() to break and address into its realname +
email constituent parts.  Here are some examples:

% python
Python 2.2.1 (#1, Apr 22 2002, 17:14:12) 
[GCC egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)] on linux2
Type "help", "copyright", "credits" or "license" for more
information.
>>> from rfc822 import parseaddr
>>> parseaddr('Mr. Bad <mr.bad@pigdog.org>')
('Mr. Bad', 'mr.bad@pigdog.org')

% python2.1
Python 2.1.3 (#1, Apr 22 2002, 18:17:38) 
[GCC egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)] on linux2
Type "copyright", "credits" or "license" for more information.
>>> from rfc822 import parseaddr
>>> parseaddr('Mr. Bad <mr.bad@pigdog.org>')
('', 'Mr.Bad')

So this is clearly broken in Python 2.1.3, and works in
Python 2.2.1.  I'll look at backporting the fix to Python
2.1 in case there's ever a 2.1.4.  But if you're using an
earlier version of Python, this will still be broken. 
Consider upgrading to Python 2.2.1.

The bug turns out not to be when there is a period in the
address, but in the plain text name. The mail address in
question is:

Mr. Bad <mr.bad@pigdog.org>

I realized this when I saw people who had different text
names from their e-mail addresses, as in:

Jr. Pickle <picklejr@someplace.foo>

This would show up as the mythical address "jr.pickle" in
mailman, and things would b0rk.

Either I need more information, or this problem is fixed in
MM2.1.  Quite often I uses test addresses like
"barry.warsaw@<wherever>" and I've had no problems with it.
