DKIM/SPF E-mail Help
First time trying to do e-mail. Been reading about DKIM and SPF but not really understanding it. Is there a clear guide on how to use it? Is this the best option for me? https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-dkim-with-postfix-on-debian-wheezy
I’m installing Discourse but my e-mails are not delivering, which means I can’t get it set up.
Thank you for your patience and assistance!
