I've been with DreamHost for about 15 years. They are a huge USA-based ISP where I have ISPConfig in my own little VPS cloud. They are a fine vendor for all needs except one: Their IPs are always on block lists. I can't take it any longer. I need to migrate to a new ISP that is not frequently on BLs, and preferably USA-based. Expand: ;TL/DR; To be specific, we have reserved floating IPs for the MX servers, but they are still within the class-C IP blocks that are owned by DreamHost and subject to abuse by random spam originators. So someone buys their services for a day, sends out spam, and the entire subnet gets blocked by some random entity (RATS, UCEProtect, Barracuda, ivmSIP, etc). DreamHost deletes their account but the damage is done, and we/I have to respond. Until the issue is resolved, and we/I have no control over it, mail to us and from us bounces, because other companies like Microsoft blindly rely on these BLs. Discussion with many of these entities is futile, some of them are scammers and hold IP blocks hostage (UCEProtect is an example) - others like Spamhous are easy to work with and quick to respond. I originally started a DIY mail server because hosted email commonly has these issues, and I wanted to avoid being affected by someone else's server problems. I started with Zimbra but felt it was inadequate. Then I found ISPConfig and have loved it ever since. But this one problem (unrelated to the software of course) continues to haunt me. How do You avoid this problem? Is Your ISP immune (mostly or entirely) to these problems? If you don't have this issue (your IPs on RBL through no fault of your own) would you recommend Your ISP? Digital Ocean says people should go through a major email provider. Those are expensive. Linode and Rackspace VPS are expensive too. I'm looking for other options. Thanks.
