I've been doing more testing and I'm seeing what I think are conflicting results?
I've sent an email from gmail to a test inbox here.
In the email header I see:
Authentication-Results: foo.umrk.org; dkim=pass
(1024-bit key; insecure key) header.i=_at_gmail.com; dkim-adsp=pass
Which seems to suggest that the incoming mail authenticated ok?
In mail.log I'm seeing opendkim report "not authenticated" and spamassassin report T_DKIM_INVALID.
Here's the log details for the email in question.
