I started using the Rackspace cloud because of Rackspace’s good reputation and of course the ability to host multiple servers on a cloud at an “affordable” price.

The Rackspace cloud gives you the ability to add multiple cloud servers on the go and resize them according to your resource needs. They bill you per hour based on the amount of resources (disk space and RAM) and the total amount of bandwidth that you use per month.

I had one server on the Rackspace cloud with 160Gb hard drive space and 4096Mb of RAM. Unfortunately, after spending several days migrating all my sites over to the new cloud server I realized that easily about 60 – 70% of all outgoing emails to clients, colleagues, friends, etc. bounced back stating that that MTA has a poor reputation. I checked to see if my IP was on a blacklist and so it was. The IP was blacklisted on spam.dnsbl.sorbs.net and still is as you’ll see here (type in

If the IP was blacklisted due to my own malicious work, I would take responsibility for it but this is how I got the IP in the first place. Not only that single IP is blacklisted but the entire IP range is blacklisted so it is affecting thousands of users. So I contacted Rackspace support and their response was…

Unfortunately in order for SORBS to delist an entire IP range/block from their database SORBS requires a large donation, which is not something we are willing/able to do.  We can submit individual requests for customers on a one off basis only.

Thank you for contacting The Rackspace Cloud technical support.  Please let us know if we can assist you further.

It is not possible to switch out an IP on a cloud server either. If the IP could’ve been switched with a new/different one, it could solve the problem but the only way of obtaining a new IP is by deleting your cloud server and creating a new one. And how you do migrate your data? You copy it over via shell and YES, you pay for that bandwidth.

That was 2 months ago and after numerous follow-up tickets from myself and a monotonous response from them “We have submitted your IP to be delisted from SORBS but that is the extent of what we can do. Please let us know if there is anything else you need.
“, the issue still hasn’t been resolved. I’m very sorry but I cannot pay that much for a server with the fear of every email bouncing back due to the blacklisting. Many of my clients hosted on my server were frustrated due to this since their emails to their clients couldn’t go through either. Not all but many emails bounced back.

My personal opinion and recommendation is that you save yourself the trouble, tears, time and stress by choosing another, more reliable provider. Sorry for the negativity but I was quite worked up because of this but feel relieved that I’ve moved all my stuff and I’m cancelling the cloud server today with pleasure.
