    Can anyone shed light or experience on an error like this:

    Error: "550 SC-001 (SNT0-MC4-***) Unfortunately, messages from 198.*.*.* 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." while connected from *.domain.com (198.*.*.* ) to mx1.hotmail.com (65.55.92.184)

    *=various

    Any help appreciated/

    Lots of Internet Service Providers have started voluntarily blacklisting their own IP ranges to stop their customers from becoming part of Spam/Botnets. I've seen this in both US and Europe and its becoming more widespread. I've run my own home SMTP server since the early 90's (1200 baud modem ftw!) so it was a bit of a pisser to realise, I moved my SMTP needs up to a VPS server when I realised what is going on.

    I've hosted my own email servers since 2005. One of my server IP was added on their list once. I needed to fill a form to request lifting the block. It took 6-10 months until they lifted the block. Good luck.

    thanks guys for the input and ikstob, thats brought back memories of 14.4, then nasty ISDN and netscape 1.0 and excitement at animated GIFs. Good times!

    Mailing is tougher out there than ever and this one threw me for a bit - I think its the ISP reputation that causes this and i found the answer meanwhile anyway here www*rackaid*com/resources/hotmail-blacklist-removal/

    cheers

    Just check with your ISP. They are the right person to raise a request to Hotmail to release the IP. Of course you will have to share more details asked by Hotmail in their request form. Also check in mxtoolbox.com and see in how many RBLs your IP is listed. I suggest you/ISP to delist your IP from these RBLs first before your contact Hotmail. For me, delisting the IPs from RBLs usually fix the Hotmail mailing issue.
