MxToolbox Updates: New Mobile/Tablet-Optimized SuperTool in Beta

MxToolbox will soon beta test a new and updated version of our SuperTool (Beta8). Some SuperTool users will receive access to this beta version, while others will continue to use the existing SuperTool.  Be on the lookout for the upcoming changes.

The SuperTool streamlines all of your MX record, DNS, blacklist, and SMTP diagnostics into one integrated tool. Everything you need to assess your business domain’s status is found with this free tool.

Our Beta8 rollout centers on increasing multi-device usage and ensuring a better, more enjoyable experience across all devices. Upgrades will be especially noticeable for users on both mobile and tablet options. From phone, tablet or laptop, the new and improved SuperTool will help retrieve all the information you seek with the aim of a better user experience than the current SuperTool.

If you receive the Beta8 version, congrats! Any feedback you could provide our team will be greatly appreciated. Please send your thoughts, concerns, and recommendations to:


SPF Tool and IPv6 Updates

SPF Tool and IPv6 Updates

To continue our support of Email Delivery and Deliverability, MxToolbox is adding IPv6 support (Internet Protocol Version 6) to our SPF Tool, with more tools to come online later. When a user runs an SPF lookup, this update changes the lookup behavior for MX and A records that are specified within an SPF record (as tags).  Now,  SPF lookups will also check for AAAA DNS records and their resulting IPv6 addresses. Previously, the SPF tool only looked for IPv4 addresses when MX and A tags were present in an SPF record.  


IPv6 is the most recent version of the Internet Protocol—the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Web. It was ratified as an Internet Standard in 2017 and allows for larger addressing space. Every computer, smartphone, and any other device connected to the Internet needs a numerical IP address in order to communicate with other devices. Compared to its predecessor, IPv6 can handle packets more efficiently, improve performance, and increase security.

While, IPv6 has been around for decades, IPv6 addresses are now being actively used in email delivery.  MxToolbox is here to help with the transition to IPv6.  MxToolbox’s research of the current outbound email space shows that adoption has largely been among the free webmail providers such as Gmail and  Additionally, 25% of the Alexa Top 1000 websites are currently reachable over IPv6 networks.



Threat Investigation in Delivery Center

Email delivery is under assault by spammers and hackers world-wide.  Your brand and domain name can be leveraged to send spoofing emails, malware and spam to your customers, your suppliers and even to random strangers.  Unfortunately, the potential for abuse is no longer restricted to larger companies as hackers and spammers attack smaller, less protected companies.  Regardless of the size of your business, you need to protect yourself.  Several small businesses using MxToolbox Delivery Center have recently discovered that as much as 90% of the email volume reportedly coming “From” their domain is spoofed, leading to blanket denial of their email delivery.  Any company can have their business completely crippled by this type of spoofing.  How do you investigate and prevent email spoofing to improve email deliverability and protect your business?

DMARC Record Missing Alerts

Have you heard of DMARC?  It is the newest way to protect your email delivery and online reputation from delivery failures, misconfigurations and fraud and phishing attempts.  If you aren’t using DMARC, you are at risk from email delivery failures.  Learn more about DMARC, DMARC Compliance and Email Delivery.

Since DMARC is such a pivotal technology, we have decided that our customers need to be alerted when it is not configured.   Therefore all MX record lookups will show a critical warning when a DMARC record is not found (see below).  Paid users with MX monitors will receive critical alerts that a DMARC record is missing or misconfigured for their domain.

MxToolbox experts feel that DMARC is critical to your business success.  Our team is ready to help you with your DMARC configuration and transition to a focus on proactive email delivery management.  Our most recent products MxToolbox Delivery Center and MxToolbox Fraud Center leverage DMARC to improve your email delivery and protect your brand from email fraud.

Announcing MxDelivery Center

The only constant in the email world is change…

In the Dot.Boom era, most people discovered email for the first time.  Quickly thereafter malicious individuals discovered how to exploit the new technology for profit with unwanted email: SPAM.  So, businesses created blacklists, lists of IP addresses implicated in the distribution of SPAM, to stop them.  At the same time, a need for legitimate business to know if they were flagged as SPAM and blacklisted arose, and MxToolbox has been informing businesses of their online blacklist reputation ever since.

Over the last decade and a half, legitimate businesses started to employ email filtering and 3rd party mass email companies to keep their email servers off of blacklists and improve inbox delivery.  In addition, new techniques and standards were created to help businesses manage these relationships: SPF, DKIM, DMARC, etc.

What do these standards do?

SPF tells the world what IP addresses and Domains can send email on your behalf.

DKIM electronically signs emails you send to prove that they were actually sent by you.

DMARC provides a framework for how a receiver of your email should process any discrepancies they see with SPF and DKIM and how they should tell you about them so that you can improve your email deliverability.

These technologies fit together nicely, but understanding them and reporting on it is complex.  So, we thought we’d help…

Our Suite of DNSSEC Tools

Recently, you might have an uptick in Denial of Service attacks or problems with root domain servers.  DNS, while the backbone of the internet, was always easy to spoof with man-in-the-middle attacks and other exploits.  To reduce the effects of these exploits, smart people in the industry created a standard to help secure DNS through a bolt-on security framework called DNSSEC.

Basically, DNSSEC enables an organization with DNS servers to vouch for a DNS entry that it serves to a requestor by signing it.  This is similar to new standards for other early unencrypted Internet protocols communications, like DKIM for email.  Using DNSSEC is like DKIM in that a provider publishes their signature in a separate DNS entry that can be queried by a DNSSEC aware client.  Clients in this way guard themselves against false DNS entries seeking to exploit them.

MxToolbox wants to make it easier for you to keep up on the latest security and networking standards, so we’ve created a suite of tools to help you with DNSSEC.  Check them out:

  • DS –  identifies the Delegation Signers (DS) for the specified domain
  • DNSKEY – returns the DNSSEC records for a domain
  • IPSECKEY –  returns the public key that resolvers can use to secure data at the IP layer using IPSEC
  • NSEC3PARAM – used by authoritative DNS servers to calculate and determine which NSEC3-records
  • NSEC – identifies the next secure (NSEC) record for the specified domain
  • RRSIG – identifies the Resource Record Signatures for the specified domain

New Subnet Management & Calculator Tool

MxToolbox has just launched a new Subnet Calculator tool.  It does basic subnet calculations like many online tools, but with an MxToolbox twist.  It also displays a list of each IP in the subnet and automatically does the reverse DNS lookup for you.  Real data, at your fingertips, free for all of our users.

Subnet Tool
We’ve designed this tool with service providers or larger customers in mind who manage blocks of IP addresses. For our blacklist monitoring customers, we also overlay your blacklist status and reputation data right in top of your subnets. You can also easily save “Name” information directly into the results to make it easier to keep track of things, if your reverse DNS names are not descriptive enough.

All logged in users (free, basic, or pro) will have a history of their subnets available in a drop down menu for easy access.
We are hard at work on more exciting features, and will keep you posted here.

MxToolbox adds Custom Filtering

We have been hard at work behind the scenes at MxToolbox getting ready to launch several new features, the first which is called Custom Filters. The MxToolbox tools are now recording each part of a lookup as separate piece of information. By doing this can now allow our users to ignore any piece of a lookup that might not be important to their organization.

The Custom Filters preference pane

The most common use of the custom filters we predict will be for users to ignore blacklist alerts for lists that they are not interested in being notified for, however the feature is available for all of our monitoring lookup types and can be tailored to fit specific monitoring needs.

Custom Filters are only available for customers with at least a Basic account which starts at $20 per month. Basic packages also come with additional monitors, more frequent monitoring, our bulk add tool, and a tag based dashboard. Visit our upgrade page to see the full details to our Basic and Professional packages.
