FMP's mail and web server is a virtual server at Linode. We run half a dozen Mailman lists or so, all opt-in lists for a couple of non-profits and small business customers, all of which have been running successfully for many months. Today I got a large number of unsubscription notices from one of our lists, all of them for addresses at hotmail.com, msn.com and outlook.com. They contain the following text:
hotmail-com.olc.protection.outlook.com [104.47.44.33]: >>> MAIL FROM:<aftm-bounces+clarkson-66=hotmail....@lists.fmp.com> BODY=8BITMIME SIZE=5492 <<< 550 5.7.1 Unfortunately, messages from [198.58.125.221] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3140). You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors.
