 In eugeni's /var/log/mail.log, we have lines like
 {{{

 edu.mail.protection.outlook.com[104.47.41.36]:25, delay=1.7,

 }}}

 I noticed because I was subscribed to one of our mailman lists at my
 mit.edu address, and I was strangely not getting any of the mails to the
 list.

 I went to the sender.office.com link and clicked, and it emailed me a url
 which I then clicked on too. It said that the block would be removed
 "soon". Soon has not occurred yet.

 I am thinking that this issue, plus also related ones like #34134, are
 caused by the big ramp-up in mailman abuse recently, which is #34256.
