No. We do not provide email hosting. We provide a mail gateway service. As your email passes through our server, the spam is filtered out and the legitimate mail is delivered to your existing mail server.
Yes, you will need to make a small change to your domain’s DNS records to use our service. You must own your domain or have access to these DNS records in order to use our service. If you have a free email account (Gmail, Yahoo, etc…) or an email address provided by your ISP, you cannot use MX Guardian.
An MX record is a special kind of DNS record that controls where Internet email should be delivered for your domain. It usually points to the IP address of your mail server, but by changing it to point to us, we are able to filter your mail before it reaches your server.
You will not notice any significant delay in the delivery of your messages. Most messages are received, processed, and sent back out within a matter of seconds.
No. We only filter your incoming mail. Your outgoing mail will not travel through our servers.
There are several options. By default, junk mail is kept in a quarantine on our server for 14 days after which it is deleted. You have the ability to login and view quarantined messages at any time. You can release individual messages from the quarantine and they will be delivered immediately. Other options are to have junk mail deleted immediately, or delivered with a modified subject line so your email client software can decide what to do with it.
Yes. Our easy to use, web-based control panel allows you to login and manage your account settings on a global level or for an individual user. You can setup whitelists and blacklists as well as adjust thresholds for detecting spam.
Yes. There is a report that can be automatically emailed to users once per day at a specified time that shows what messages have been blocked in the last 24 hours. These reports can be turned off for individual users if desired.
One of the additional benefits to using MX Guardian is that if your server goes down or is unavailable, we will buffer your mail in our mail queue for up to 5 days. Once your server is back online, we will automatically resume mail delivery without any messages getting lost in the process.
We have a message size limit of 50 MB. This includes the message and all attachments. If you need to receive larger messages, please contact us.
You can configure your router, firewall, or mail server to only accept email from MX Guardian’s IP addresses. Our current list of IP addresses can be found here.
Unfortunately no. MX Guardian works at the domain-level so you need to own a domain name and have access to the domain’s DNS servers to use MX Guardian.
No. MX Guardian works with dedicated and non-dedicated mail servers. As long as your mail server is connected to the Internet and uses the SMTP protocol, it will work with MX Guardian.
Yes. Any SMTP-compliant mail server that accepts messages from the Internet can be used with MX Guardian.
Yes. Although Office 365 has it’s own spam filtering built-in we have many customers using MX Guardian as an extra layer of protection.
Yes. We can deliver mail over IPv6 if your mail server has an IPv6 address.
The monthly price depends on how many users you have in your account. If you have multiple domains, the price is based on the total number of users across all your domains. There is no cost to add a domain. See our pricing page for more details.
A user is any person that receives email and has a mailbox on your mail server. If a person has multiple email addresses going to the same mailbox, those can be setup as aliases in MX Guardian so you don’t get charged for them. You can have as many aliases as you need.
Unfortunately, we only have a monthly payment plan. The monthly price can flucutate depending on how many users you have in your account. Therefore, we only bill monthly.
We accept Visa, MasterCard, Discover, and American Express. We do not accept any other payment method.
There is no contract and you can cancel at any time. You can cancel your service by logging into your account and clicking the “Cancel my account” link on the Billing tab. Before you do this, please make sure your MX records are not pointing to our servers.
