Notification emails to Microsoft/Hotmail/MSN failing
I just did a routine check of our outbound mail logs for the notification emails the forum software sends when people subscribe to them. If you are using a Microsoft provided email account you may not be receiving email notifications from the forum. It looks like Microsoft network spam filters are discarding the emails:
"message": "5.7.1 Unfortunately, messages from [22.214.171.124] 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.
get the same from msn.com
I will see what is possible to do to improve the situation.
