Internal bounces on campaigns sent to hotmail domain

Hi,

I have never had the chance to send a successful campaign to a hotmail email. I always get the below reason for the failed send-out.

550 5.7.1 Unfortunately, messages from [50.31.49.42] 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. [BN8NAM12FT035.eop-nam12.prod.protection.outlook.com]

It happens all the time.

Is the Mailwizz app being blocked by the hotmail server?

Hello,

It says your SMTP IP network is Blocked on Hotmail.com

You need to check your SMTP IP pool.

Thanks,

VPul.

Hi, can you kindly elaborate? Thanks a lot!
See - Please contact your Internet service provider since part of their network is on our block list (S3140).

This says your ISP Network IPs are blocked on hotmail/outlook, so Emails are not delivered.
