New MX Records for DNS Redundancy

On July 1 we experienced DNS failure of our top level mailhop.org domain which impacted customers to a varying degree before ICANN resolved the problem. Part of our mission statement is to minimize all single points of failure for your email service. As a response to this problem we have created three new DNS zones that you should immediately add to your DNS record.

The mailhop.org DNS is handled by DYN, we have now added Amazon’s Route 53 and Cloudflare as redundant DNS providers and have created multiple zones for redundancy. Not only are these domains registered with difference registrars, they are also utilizing independent TLD’s (Top Level Domains) and different DNS providers.

To you should configure your DNS so that your custom MX record or mx1.mailhop.org is set to priority 10 and the additional records should be configured like this:

Email Gateway / Email Forwarding 

MX 10 Your custom MX Record (from customer portal) or mx1.mailhop.org
MX 20 mx1.mailhop.us
MX 30 mx1.mailhop.co
MX 40 mx1.mailhop.co.uk

Backup MX

MX 5 Your current mx record – this is your server directly or your own filtering destination
MX 10 Your custom MX Record (from customer portal) or mx2.mailhop.org
MX 20 mx2.mailhop.us
MX 30 mx2.mailhop.co
MX 40 mx2.mailhop.co.uk

We are urging customers to make this change as soon as possible to minimize any future DNS related issue.

Stop ransomware, phishing, spoofing, fraud and other sophisticated email attacks. Email is the number one vector for sophisticated threats that are targeting your organization. These days its people rather than infrastructure that are the targets. Traditional spam filtering struggles to keep up with these new attacks, leaving your company at risk, which is why we are introducing Advanced Threat Defense, a layered approach to message security.
