Email Defense Mail Filtering

I am getting buried in all of this spam. Is there a way I can filter this junk mail?


Nobody likes spam. Every day, you waste time looking through spam emails trying to find your important emails.

While most web hosting services, including ours, include basic virus scanning and spam filtering, a third-party spam filter can make a huge difference with the amount of spam you receive.

Here is a guide on what Email Defense mail filtering is and how you can purchase it and use it with your domain web hosting.

What is Email Defense?

Email Defense is an email filtering service the scans your incoming email for spam. The service looks for potential and know spam characteristics and quarantines any potential threats.

And not just spam. Email Defense will also look for malware, viruses and phishing attacks. Email Defense is constantly checking for spam and updating its filters to block potential threats before they can do any harm.

Another great benefit of Email Defense, is that if, for whatever reason, your mail server is unreachable, it will queue your mail until it can be delivered. You can access this queued mail from the Email Defense interface.

How does Email Defense protect my mailbox?

While the service is quite complex on the back end, essentially what email defense does is redirect your mail to their filtering servers, where it checks your emails for known treats and potential spam or phishing. It will also look out for potential unknown threats. Any mail that looks suspicious is put in quarantine for you to review later. Mail that is known to be dangerous is rejected and any safe mail is then forwarded to your mail server.

How do I manage my spam quarantine?

The main part of your Email Defense dashboard is the spam quarantine. This is where the filter places mails that it flags as potential spam. You can use the quarantine to help train the filter by releasing good mail from quarantine and sending it to your mail server, or by removing it and flagging the sender.

The Spam quarantine app icon.

As mentioned here, you first need to log into your email defense dashboard and click on the Spam quarantine app.

Once you open the app, you will see a list of all the mail the filter has flagged and quarantined.

An example of a few quarantined emails.
The quarantined email options menu.

Clicking on the drop down menu for each email will show the options menu. From here, you can choose what to do with the email. You can choose to block the sender permanently or add them to your allow list.

You can also delete the email from your quarantine (Remove from quarantine) or push it to your mail server (Release from quarantine).

You can also manage several messages at once by using the check box to the left of each email and then using the bulk actions at the bottom.

It is a good habit to check this quarantine from time to time (once a week, perhaps). The more that you interact with the quarantine, the better it will get at sorting out your emails. It is also the first place you should check if you did not receive an email you were expecting.

How do I create accounts for my other mailbox users?

The interface for adding new email users.

You can manage your user accounts from here, and you can add a new user by clicking Add in the upper left hand side. You can create and account for each of your email users so they can manage their own spam quarantines.
