I am getting rejections from Hotmail
Jan 18 14:42:22 mail postfix/smtp[6571]: 046713F914: to=< helen_maryd@hotmail.com>, relay=hotmail-com.olc.protection.outlook.com[104.47.58.161]:25, delay=0.14, delays=0.06/0.03/0.04/0.01, dsn=5.7.1, status=bounced (host hotmail-com.olc.protection.outlook.com[104.47.58.161] said: 550 5.7.1 Unfortunately, messages from [167.99.151.239] 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.

I have submitted a ticket to https://support.microsoft.com/en-us/supportrequestform/8ad563e3-288e-2a61-81...
Not sure why they are blocking me. Not on any other blacklists per mxtoolbox...
Anyone else experienced this? How to resolve?
My mail server is on Digital Ocean if that makes any difference.
Thanks for any help
