Php web application and reply to email to call function

Question

I am developing a web application in php using codeignitor. I want to execute the "reply to this email approved in the body of the email to update the application." feature.

Currently, wen web applications are sending an email for approval, we can directly reply to email so that the application starts updating after sending a response. How is this feature implemented? I searched on the Internet, could not get any clues.

Answer 1

You can create a script to poll a mailbox for a specific email address and approve the email messages to which it received a response. Then you will need to configure cron jobs to run the script periodically.
