I am using Microsoft mail account (hotmail) and I observe similar
problem. Many messages are sent to "unwanted" folder.
I don't know how to add IBM-MAIN to safe senders. The only thing I can
do is manually add each address, message by message.
However it is not effective - a lot of manual work. I doubt MS service
honour my requests.
Last, but not least: for regular mailing I use Thunderbird. But for
"un-spamming" I have to use web browser interface.
BTW: I use this mail account almost only for IBM-MAIN and RACF-L.

Microsoft Exchange has started quarantining too many messages from this listserv as
"phishing". It is several per day; one day there was 16.
Adding [email protected] address to the Safe Senders list doesn't work because
of how the messages are sent "on behalf of" (i.e. the sender not the listserv).
The email support team tells me that the reason the filter is catching them is
they have dmarc failure. One example is the message below. It failed with:
Authentication-Results: spf=pass (sender IP is 130.160.0.25)
smtp.mailfrom=listserv.ua.edu; dkim=pass (signature was verified)
header.d=UA.EDU;dmarc=fail action=none header.from=COX.NET;compauth=fail
reason=001
But another message from the listserv passes:
Authentication-Results: spf=pass (sender IP is 130.160.0.25)
smtp.mailfrom=listserv.ua.edu; dkim=pass (signature was verified)
header.d=UA.EDU;dmarc=pass action=none
header.from=LISTSERV.UA.EDU;compauth=pass reason=100
On the other hand, messages I send to the server have mixture of pass and fail,
and they aren't getting quarantined.
Does anyone know if this is a problem originating before it hits
listserv.ua.edu, or is it a problem in listserv.ua.edu?
The mail people are claiming it has to be fixed at the server end.
