Our server's IP address is blacklisted by the provider of hotmail.

We can't find any solutions. We followed up with all the instructions they gave us in the DEAMON email link, but it's not enough - the IP is still banned.

Do you know how to contact them or how to solve this problem at least easily?

Hotmail, which is operated under Outlook.com now, is provided by Microsoft. You can request they remove your IP address by completing the form here (this may require signing up for Outlook.com first).

It will take a few days for them to investigate the report, and if your IP address was not associated with sending Spam, you'll receive an email back from their support team. It will then take another 24-48 hours for the IP address to be fully unblocked in their system.

You should also test your IP address in a multi-RBL check site like this one. Visit each site that your IP address is listed in and test it there to see what message they relay back. If there's something you can address, then do so and request that they remove your IP address from their list.

It may also be wise to setup and configure SPF and PTR records in the DNS for your mail server, as well as DomainKeys Identified Mail.

    I was also blacklisted and actually wanted to give up on it, but then found this URL. It fixed the problem in a day.

  • Use the link that Tobias provided to the request form, since the URL has since changed.
