The Email Approver System mentioned in this article acts as a email polling system that fetches emails and complete assignments periodically based on configurations.
Figure 1: Setting up the listeners
There can be more than 1 listener set at any point of time. Each listener, technically, will be a process instance that repetitively run in a loop until terminated by the user.
Configurations
Figure 2: IMAP Email Settings
IMAP Email Settings must be configured so that it will check a specific email's inbox for new incoming mails.
It is important to create a dedicated email address to receive such "response" emails so that the the execution code block does not spend too much time going through irrelevant emails.
Figure 3: Listener Settings
Listener Settings needs to be also configured to determine the frequency of checking and emails to be matched too.
Take note that the checking interval is also subjected to the Deadline Checker interval set in Joget Workflow's system settings.
Figure 4: Listener Settings - Subject and Content
Subject and Content Patterns are very important.
Make sure that you match the content of the outgoing mail that you send out in your other Joget Workflow App.
It may take a few tries to get it right so you can turn on the Debug Mode to get the relevant logs for debugging purpose.

If there is a match based on the subject or the content, the code block will then retrieve the email's sender information (email) and matches it with an existing user in the system. If there's a match with an user and if there's a further match with the particular user's assignment, then it will then proceed to complete the assignment.
While completing the assignment, depending on the configurations set, workflow variables' values and/or form data values can be set too.
Figure 5: Optional - SMTP Email Settings for Auto Reply
You can configure this section if you want the listener to automatically reply to email that it matches.
