Hi List One of our mail platform IP has once more been hit by an outlook.com blocking:
host outlook-com.olc.protection.outlook.com[104.47.4.33] said: 550 5.7.1 Unfortunately, messages from [157.161.12.116] weren't sent. Please contact your Internet service provider since part of their network is on our block list (S3150). You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors. [AM5EUR02FT063.eop-EUR02.prod.protection.outlook.com] (in reply to MAIL FROM command) According to MX-Toolbox that IP is not listed anywhere. According to our report on: https://sendersupport.olc.protection.outlook.com/snds/ipStatus.aspx "All of the specified IPs have normal status." On View Data there are occasional 'trap' hits for that IP and the history show < 0.1% but 9 red days. We also had a spike with 2% trap hits, but that is not flagged as 'red day'. So somehow I don't quite understand what 'red day' means and what could cause the IP to be blocklisted right now I think we are doing a pretty good job keeping our mailserver clean from phished accounts. Anyone with more insight?
