A few people have indicated to me that they are NOT seeing issues with
GMail. Just to be clear, what I am seeing a pattern of gmail users
sending email to mailinglists and every outbound email to other gmail
users logs this:

It's as though Gmail wants a mailinglist to authenticate to send email
to gmail recipients. :-)
It's not persistent, it's just happened a few times in past 2 days,
generally in the AM.
