Most of us would use POP mail when we are using our host's email. What kind of email protocol is used when you install a script and the user fill out the contact us form and automatically, the email is sent to you. I am asking this because whenever I install a script such a wordpress or SMF forum or VB, the server settings for the email is not asked. I only enter the mySQL settings so I would assume this is an email that is set through mySQL. Please correct me. I am right? Anyone can shed light on this?
