sez:
There are three occurrences of the following, associated with
Received: entries, in the header:
(No client certificate requested)
I'm guessing that those are harmless.
Yeah, I suspect that's from a TLS connection between client and
server, and the client didn't provide a certificate which is
normal.
This seems to be a common occurrence in emails I send to
@stanford.edu, at least.
There's also an "spf=softfail" in there.
Authentication-Results: mx.google.com <http://mx.google.com>;
spf=softfail (google.com <http://google.com>: domain of
transitioning dnc2dnc(_at_)gmail(_dot_)com <dnc2dnc(_at_)gmail(_dot_)com>
does not designate 171.67.219.78 as permitted sender)
smtp.mail=dnc2dnc(_at_)gmail(_dot_)com <dnc2dnc(_at_)gmail(_dot_)com>;
dkim=fail header.i=@gmail.com <http://gmail.com>;
dmarc=fail (p=NONE dis=NONE) header.from=gmail.com
<http://gmail.com>
Note that 171.67.219.78 is smtp-grey.stanford.edu.
Huh. I'd be interested in looking at the whole Received:
header chain, but maybe I don't understand what is going wrong;
it almost seems like smtp-grey.stanford.edu is the one
originating the email and that doesn't make sense to me, if
you're submitting directly to gmail. But yeah, I suspect the
failing SPF, DKIM, and DMARC tests is what is causing the
problem.
Appended to the bottom of this message. I redacted all the
personal information I could see. Hopefully I didn't go too far.
NOTE: the same spf=softfail message as above also appeared in a
message I sent while still using sendmail for outbound email!
Okay, this header is actually defined in RFC 5451, see here:
https://tools.ietf.org/html/rfc5451
Is that still valid? The top of the linked page indicates that
RFC 5451 is obsoleted by RFC 7001 (in turn updated by RFC 7410).
But I am still puzzled.
I think your original point about Proofpoint being stingy is key.
One of my messages tagged as spam had just this for its body:
--047d7bfcf7d06fb18e050dadac3b
Content-Type: text/plain; charset=ISO-8859-1
ETA: 19:45. Sorry about this!
--047d7bfcf7d06fb18e050dadac3b
Content-Type: text/html; charset=ISO-8859-1
Content-Transfer-Encoding: quoted-printable
<p dir=3D"ltr">ETA:=A0 19:45.=A0 Sorry about this!</p>
--047d7bfcf7d06fb18e050dadac3b--
The Proofpoint bit in the header was:
X-Proofpoint-Virus-Version: vendor=fsecure
engine=2.50.10432:5.13.68,1.0.33,0.0.0000
definitions=2015-01-27_04:2015-01-27,2015-01-26,1970-01-01 signatures=0

adultscore=0 bulkscore=0 classifier=spam adjust=0 reason=mlx scancount=1
engine=7.0.1-1402240000 definitions=main-1501280032
The Subject: was tagged with a triple-score SPAM:
Subject: [SPAM:###] Waaaaay late!
This was sent using GMail's web interface, so it's about as
"legitimate" as it can be. No failing SPF, DKIM, and DMARC tests
(as far as I can tell).
I'm beginning to think that Stanford assumes all email from
outside @stanford.edu is automatically suspect. (But why a
message that looks *more* like it's coming from a compromised
user should pass is beyond me.)
