IP blocks blacklisted and unresponsive support


what is your experience with OVH ip addresses being blacklisted on major RBLs and at Microsoft?

On 20th December OVH got a /24 listed at Spamhaus RBL because some spammers used some other IP addressess in this range for their activity. Unfortunately in this range my /28 was included but Spamhaus wont talk to me directly as despite having a dedicated block of IPs the abuse-mailbox provided to ripe is

A week later - this block is still blacklisted with apparently no actions being taken by OVH. Despite filing ticket to support and writting to OVH abuse whole range is still blacklisted with no message from OVH what actions were conducted. After a brief talk on december 24 OVH provided a new range of IPs to me, but the whole range was already at Microsofts blacklist (“Blocked due to user complaints or other evidence of spamming” at Smart Network Data Service) - i.e. not really usefull to send any emails from. I did order additional Failover IP only to find out that they are blocked as-well.
To add insult to injury it seams that polish OVH branch is having a day off today as every attempt to phone call them (since they aren’t answering to support cases filed through panel) ends with IVR saying “this option is currently unavailable. please file a support case instead”.

Anyone is facing the same problems or have any idea what can I do to make OVH do their work and ensure every party involved that they can handle abuse complaints properly?


I’m facing the same problem since the beginig. Alway trying new FO Ip with some luck somtimes.
It is verry time consuming.


FWIW, this is useful:
The hotmail/ link does work, takes a couple of cycles, but this is the price to pay to “join the internet”.


Hi @MarekP

Situations like these are very common since OVH IP addresses are widely used, you should not be impressed by it. Both at OVH and at hundreds and thousands of suppliers you will encounter similar problems.

All you have to do is the following below.

  1. Securize the server with your closest SysAdmin (System Administrator)

  2. If you have the experience, carry out a complete scan in search of viruses, malware among other anomalies (even if the server is clean)

  3. Save diagnoses or reports as evidence so that it can be explained or attached to the corresponding forms to list the IP addresses of the black lists

In this way you also make sure that the server is not infected and rule out if the IP was already really blacklisted

  1. When requesting to list the IP of providers such as Spamhaus, this will take 24 to 72 hours

If the server is infected or you have a website that is compromised, the IP or IP range will be listed again

Take into account that OVH does not offer support to this type of event, it is not responsible, only and exclusively they sell you the server but you are responsible for carrying out this type of work or the person you hire for it

I hope I have clarified or helped you with your situation
