Hi,

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.

SNT0-MC2-F20.Snt0.hotmail.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?

Cheers

Hello,

It sounds like Microsoft have blocked a range of IP Address that are with your ISP.  Contact your ISP, report it to them and ask them to arrange the removal.

This may also be worth a read:

You can try emailing the Microsoft delisting address but as they've blocked a range it will probably have to come from your ISP.

Hi,

I have spoken to the IP and they say because i am using the exchange server, they can't do anything about it. They have however added PTR records etc and this has not resolved the issue still. I guess i will just have to bide my time now!
