Was the message from the list software or from a Microsoft system?
There's possibly one subscriber that has configured their
Exchange/Outlook account to forward e-mails to a Gmail account, and
forwarding as implemented by Microsoft apparently isn't done correctly
and so "SPF" checks run by Gmail are failing.
I tried to send a message to this list about this topic back in November
but it never made through, perhaps it was filtered because it quoted
some of the error messages.
