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)?
thank you!

Hi,
you are right, you need a reverse DNS record. DigitalOcean sets this record based on the hostname of your droplet automatically. You can check your settings with the command:
If you wish to update your rDNS record, you can rename your droplet in the control panel:
And I recommend you to create SPF and DKIM records, too.
You’re PTR should coincide with your hostname, just ask DO to update your PTR.
