Hi, I hope someone can help with this. All of a sudden I can't send to Hotmail addresses - was working fine up until yesterday. Here's the full message that I get:

The following message to <jakenicoll@hotmail.com> was undeliverable. The reason for the problem: 5.1.0 - Unknown address error 550-"5.7.1 Unfortunately, messages from [134.153.136.23] 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. [DB3EUR04FT045.eop-eur04.prod.protection.outlook.com]"


Reporting-MTA: dns; esa03.ucs.mun.ca

Any thoughts or help is much appreciated. Got the same result with another friend who has a Hotmail account. Thanks!

Thanks Adrian

This is a problem related to your email provider esa03.ucs.mun.ca. The Memorial University probably has a IT department that manage the email server. I think you should contact them and let them know their server has been blocked by Hotmail.

Thanks a lot Danny. I spoke to them today and apparently someone sent out a lot of spam so Microsoft blocked one of their servers. They said they're working on the issue. Cheers, Adrian
