There are software like XRumer but those doesn't work posts those bots made are easy to recognize. Those cheap vps providers have this problem too. I have 2 vps at WeLoveServers but it seems port 25 is close by either data center (That's the official story ) or by themselves (what I think). Their whole IP range has been blacklisted for months.

I wonder how they got those severs at Server-Verleih I mean from data centers. Those were good severs. I had a keyword research software running and has no problem at all. I have it in my paid vps to and these were no difference performance wise.
