Here's 1 set from the header of the above message: X-Proofpoint-Virus-Version: vendor=fsecure engine=2.50.10432:5.13.68,1.0.33,0.0.0000 definitions=2015-03-01_03:2015-02-27,2015-03-01,1970-01-01 signatures=0 X-Proofpoint-Spam-Details: rule=spam policy=default score=99 spamscore=99 suspectscore=7 phishscore=0 adultscore=0 bulkscore=0 classifier=spam adjust=0 reason=mlx scancount=1 engine=7.0.1-1402240000 definitions=main-1503010244 It's pretty clear why they tagged my message with 5 "#"s. 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. 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 dnc2...@gmail.com <dnc2...@gmail.com> does not designate 171.67.219.78 as permitted sender) smtp.mail=dnc2...@gmail.com <dnc2...@gmail.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. Might this be the smoking gun? Bob _______________________________________________ Nmh-workers mailing list Nmh-workers@nongnu.org https://lists.nongnu.org/mailman/listinfo/nmh-workers
