Email Filters (sometimes referred to as "site filters") from version 2 have been changed in version 3. Automation handles this now.
Automation allows you to control the flow of the software, by specifying what actions occur as a result of conditions being met.

For example, if an email is submitted to support@abc.com, we can capture that with Automation, and assign a specific department, user, etc.
Visit Administration > Automation:
If you installed a fresh copy of version 3, you'll see a few default automations in the system already - each of which handle the most basic, and commonly occurring scenarios.
You can modify the default automations, or add entirely new automations.
Our example below auto-assigns the "Technical Support" department whenever an email is sent to support@abc.com:
If you are upgrading from version 2, you may have a lot of automations present - many users prefer to wipe everything and start clean. To do so, click the "Reset to default" link in the upper-right corner of the Automation page:
