I'm getting a problem when e-mailing domains hosted by Microsoft - Hotmail, MSN, Outlook etc. Messages from my IP address are being blocked it seems but i've done a spam lookup and found i'm not on any spam lists. I've also submitted a ticket to Microsoft who say my IP isn't blocked and should be fine... Below is one of the example errors.
com gave this error:
SC-002 (SNT0-MC2-F20) Unfortunately, messages from 176.35.142.XXX weren't sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider to http://mail.live.com/mail/troubleshooting.aspx#errors
I've replaced the last part of my IP, but if it will help, I'm happy to post.
Any thoughts on what i can try?
