email goes to spam (gmail), PHP
i managed to make sendmail work and i can send email out with mail() in PHP. however that email always goes to spam. my domain is new, has never been used before. i read that i have to create reverse DNS (i really have no idea how to do it) to avoid emails to be delivered to spam folder. does anyone know what exactly do i have to do to see email sent from my php script to appear in INBOX (gmail)?
