This page is, for now, notes towards trying to configure our outgoing email servers so that at least GMail won't bounce notifications from apps like phpBB. The primary return-address domains I want to configure are:

  • hypertwins.org
  • woozalia.com
  • wooz.dev

There seem to be several necessary anti-spam protocols: SPF, DKIM, and DMARC.

For clues, I can look at the configuration of toot.cat -- I'm pretty sure we configured it with all three.

SPF (Sender Policy Framework)

SPF is relatively simple, I think? Last I remember, there's a web tool to help build the necessary TXT records... but I think those domains may already be configured. Will check that.

DKIM (DomainKeys Identified Mail)

This has two parts:

  • public key in domain's DNS record
  • public key attached to email somehow (shouldn't that be "email signed by private key"?

DMARC (Domain-based Message Authentication, Reporting and Conformance)
