Content Filtering

« Back to Top

Content Filtering allows for rules to be setup that can specify what to do with certain emails. A rule could be setup to delete all email coming from a particular email address, move it to a particular folder or mark it as read, among other things. Custom email filters can be created by selecting Content Filtering from under the Filtering folder tree.

After clicking on New, a variety of different options can be chosen to create specific filters for your email.

Step 1 - Filter Criteria

In this step of the wizard, choose the type of things that the filter will look at. Multiple criteria can be chosen, and you can choose in the next step whether all criteria must be met, or only one of the criteria for the filter to activate. Click Next when the criteria have been selected.

Step 2 - Filter Type and Criteria Details

Choose whether this filter requires addtional criteria before an action is performed. Then choose whether you will be using any wildcards in your search strings. Usually, wildcards will not be necessary, but there are times when some people may want them.

For each of the criteria you chose in step 1, you will be able to enter details. Many types of content filters allow lists of items to be entered in, and these will be indicated. For example, if you chose to filter by the From Address, you can enter multiple email addresses in the box (one per line) and if a message is from any of them, that criteria will be met.

You also have the ability to reverse the logic of a specific criteria item by changing the "matches" box to "does not match." Click Next when done.
