I've noticed that the big mail outfits don't take complaints seriously from small volume-mailers. They seem to assume that you're either a big mail outfit with a ton of volume to feed their algorithms or you're spam. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com Midwest-IX http://www.midwest-ix.com ----- Original Message ----- From: "Joseph Jenkins" <joe@breathe-underwater.com> To: "Robert Story" <rstory@isi.edu> Cc: "NANOG" <nanog@nanog.org> Sent: Sunday, May 10, 2020 8:47:23 AM Subject: Re: anyone on from hotmail.com, msn.com, live.com smtp? No not at all, just replaced with a random address. So nothing from MS as of yet, best I have gotten is these two addresses to go and file complaints. It's been 2 days with no response, MS isn't so attentive it seems. https://sender.office.com https://support.microsoft.com/en-us/supportrequestform/8ad563e3-288e-2a61-81... So at this point we are just queuing up the messages waiting for MS to allow us to send again. What a pain.
