Hi We are having trouble sending Emails

keep getting this message

host eur.olc.protection.outlook.com[104.47.6.33]

said: 550 5.7.1 Unfortunately, messages from [208.91.198.28] 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

Usually when this happens your public IP addy has been blacklisted cuz a previous user of that IP was detected spamming. All you can do is re-sync your router to try to obtain another clean IP addy.

However 208.91.198.28 is not an EE IP public addy.

Well, of course! BT is giving you an entirely diff public IP.
