PHP Email Ubuntu 18.04

DKIM requires some knowledge about generating certificates. However, PHPMailer’s DKIM examples should help tremendously:

DMARC is just a record you add to your DNS after you’ve done SPF and DKIM. This wizard I found can help create this:

I also found which will help you verify DKIM, SPF, and DMARC.

Google’s answer here gives some other tips to take a look at: I haven’t tried out Google’s Postmaster tools, but Gmail itself does provide indication if DKIM and SPF pass.
