Hi,

The functionality is available in the community edition also, all what you have to do is configure the incoming mail server under Settings -> Technical with corresponding email address and in the section "ACTIONS TO PERFORM ON INCOMING MAILS" set the value for Create a New Record? as Task

* configure incoming mail server
* configure create new record as Task

Also you have to configure the email alias inside the Project.

Thanks

The project alias field is visible on the project setting, setting tab ONLY if an alias domain is provided in settings > General settings > Discuss section
