GMail's had a p=none for a while now... months.

GMail also had an odd hiccup today.  I received a ton of bounces because:

                Apr 24 18:20:59 svr6 postfix/smtp[26753]: 2838F36B12: to=
                <xxxxxx at gmail.com>, relay=gmail-smtp-in.l.google.com
                []:25, delay=0.69,
                delays=0.26/0/0.38/0.05, dsn=5.5.1, status=bounced (host
                gmail-smtp-in.l.google.com[] said: 530-5.5.1
                Authentication Required. Learn more at 530 5.5.1
                b6sm884241igm.2 - gsmtp (in reply to MAIL FROM command))

So for some period of time, they wanted Mailman to auth as who? :-)
