I just resurrected an old thread to request an API for email when I stumbled on this thread. In that one I said I believe DH has a better handle on block lists than other companies, but I might have been overly optimistic.
For reference, I’ve been using Everyone.Net as a dedicated email host, even though I get all other shared host services here at DH. This company specializes in email, nothing else, and I use them because I originally thought that they’d do better about keeping my domains from getting affected by spammers that are completely unrelated to me except for the hardware we share.
Unfortunately all of these companies use the same RBLs and when any of those guys blocks a server, it doesn’t matter who you’re paying for email, you’re going to be just as messed up right with everyone else. (This is what we get for depending on 30 year old protocols for modern critical business needs, but I digress…)
DH would make a killing in the entire industry if they took a lead in this rather than chasing after blocks after they occur. Stop being a constant victim to the RBLs that service you. Assign specific mail server IPs to your clients who have been doing business with you for years. Make sure all of these RBL services keep their hands off of these DH IP blocks by giving them confidence that you’re going to handle this stuff internally. Get brutal on UCE/spam. Make it a specialty to sell email services to companies that have owned their domains for some number of years, and make agreements with RBLs to shutdown services to specific domains no matter what their IP blocks if you can confirm that these domains are chronic spam sources. Make arrangements with credit card companies to have spammers flagged as card abusers, so that other email service providers can see if a card belongs to a known abuser before providing services. Your typical gmail, hotmail, cox.net, and other massive hosts won’t fit in that category but a huge number of other companies will - and that will fund your efforts.
I’d be happy to host my own email services on a DH VPS if I knew that would keep my domains off of RBLs. But frankly I’m not an email server admin and I’d guess most of the people aren’t either. We want to pay “someone” for server administration, and for reliable service, which means we aren’t affected when someone else does something bad.
C’mon DH, make it happen. The spam wars started in the 90’s but we’re still victimized by the exact same abuse today. Take a lead and get industry recognition and the revenue rewards for the effort. You’re big enough now where you can do it.
