There is a lot of guessing in this discussion. Maybe have a look at your logs for OVH networks and you will see something like "distributed spam delivery system" every day. I show an example of another OVH network, which is currently spamming German users:

Background: I've built a service to analyse such traffic for my mail systems. I want to understand which companies, networks, IPs, etc. are valuable to my users/customers and which try to harm them. Based on the data I can see, that OVH is not the worst, but a really bad provider for email systems. I don't know how they get customers, but this customers are bad for their network reputation - specially for mail. @Jaroslaw try to find another/better provider for your email service. You can't fix OVH sales or customer acquisition. I hope I could give another view on this discussion which heads in really different directions Regards, Konstantin Am 21.

As for real ID, is there any hosting provider that doesn't require that? When I was buying my server at OVH, I needed to present them a photo or scan of my ID, so they know who I am. When you buy a hosting service, you are entering into a legal contract. Both parties of the contract must know who the other party is. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
