I develop a function of sending of emails in PHP (on a dedibox, OS = Fedora core5) by using the function mail($email_address, $subject, $message, $header).
PROBLEM: The mails sent arrive in the junk mail box of hotmail between-others.
How to make so that the messages fall into the "reception box" from my recipients?
I sailed through many forums and I am partly persuaded that all depends on the fourth parameter of mail().
If you know the good configuration of the $header, or of the server, I thank you in advance.
