Hi Jennifer,
Unfortunately, the Rules on outlook.live.com is where I was already creating the rules that are not doing the job. I have two rules (see image below). The first one is the important one. The rule is intended to delete any emails that contains the string "newsletter". I did this rather than your suggestion, which require enumerating the blocked domains, which I don't know until the spammers have already emailed me, and since they can invent an almost infinite number of domain names, the list could never be complete. Moreover, I want to delete messages of the form "******@anydomain.com", or really "newsletter@*" where the * is a wildcard matching any domain.
The purpose of the second "To Holding" rule was to prove to myself that Microsoft's server-side filtering preempts my rules, because if the rule were working (with the first rule turned off), all emails should end up in the "Holding" folder. What does happen is that most emails end up in the Junk folder and an occasional one that presumably wasn't identified as junk gets moved to the "Holding" folder. Predictably, and proving that my first rule can work, sometimes emails from "******@anydomain.com" do get deleted, which I also interpret to mean that the message passed Microsoft server-side Junk filtering and my rule got triggered, i.e., it deletes messages correctly if newsletter is anywhere in the email address.
While, the Rule summary above is pretty clear, here's the actual rule:
And here's the second rule, which I include because the summary above implies that it only applies to the inbox:
Finally, in the Junk Email settings, I have put no email addresses into any of the three lists (blocked, safe senders, safe mailing lists) and have turned of the two possible filters.
Therefore, I am pretty sure that my problem is that Microsoft's server junk mail filtering is moving messages to junk and not executing either of my two rules.
Suggestions?
Thanks,
David
