Hi Randy --

You're making some unwarranted assumptions:

1.  lists.tapr.org is hosted by an ISP who specializes in Mailman 
hosting.  We used to run the lists ourselves but outsourced it in 2018. 
Linode is the ISP's upstream provider.

2.  The (only) blacklist that we are on is "UCEPROTECTL3" which is a RBL 
that blocks not just our IP, or our ISP's IP, but the entire ASN that is 
assigned to Linode.  Because UCEPROTECTL3 casts such a wide net, most 
spam filters give a low weight to the UCEPROTECTL3 listing, and that 
normally doesn't cause a problem.  But sometimes the spam filter isn't 
properly configured and takes the RBL as gospel, and sometimes the 
blacklist is run by the mail ISP themselves, which is what we think is 
going on in this case with Microsoft.

73,
John
