SPF
It’s not clear to me how SimpleLogin enforces SPF policies from incoming emails ?
I also take note of the support for enforcing SPF on incoming messages.
DMARC
I can see that SimpleLogin’s source code has support for enforcing the DMARC policy (presumably from incoming domains) and quarantine mails that are rejected.
DKIM
I can see that outgoing emails have a valid DKIM signature both when sending from the mailbox to a reverse-alias, as well as replying to an email from the mailbox.
However, I’m not sure SimpleLogin is validating DKIM signatures from incoming emails. Do we need to include OpenDKIM in validation mode and/or RSpamd in our self-hosted postfix configuration ?
