If you host your own mail server (I do!), then you probably want your emails to actually reach their destination. A good first step in increasing the chances of your emails being delivered is enabling SPF.
SPF is actually the easiest thing to configure in a series of steps that you can take. I’ll soon publish tutorials on DKIM and DMARC – those require a more involved setup.
What you’ll need:
- Self-hosted mail server (Postfix on a machine).
- DNS access (ex: Cloudflare).
- Know your server IP.
- ~ 5 minutes of your time.
First, login to wherever your DNS can be configured. For this short tutorial, I’ll be assuming that you’re using Cloudflare. Adapt as necessary.
