I have the following need. I am creating a system called for a client in PHP, and everything will be registered in the MySQL database and for each answer, an email will be forwarded (via PHPMailer, for example).
I need this message to be recorded in the database as well when replying to this email. However, I have no idea how to proceed or what to look for.
I know that such a feature exists, as I have already answered some calls with this functionality. But I do not know how it's done.
Does anyone have any light on where to start?
