New feature: Reject at SPF None results about smf-spf HOT 7 CLOSED

For now, I'll leave the HELO identity out. It' very rare servers have the HELO name with SPF configured.

I can create another config flag just for that use case. It can be a good feature on is own.

Hi !

I'll look at it. This behaviour already crossed my mind.

btw: When receiving DSN's the mail from is empty and the HELO hostname is verified. Do you think this should be applied to HELO name that doesn't have SPF enable?

Hmm, haven't thought on it before.

I'd say that yes, it should be applicable also in the HELO phase if the domain identified doesn't have an SPF record. Since, it will be rejected later for sure.

But in the other hand, I don't know if all mail servers identify in HELO with the same domain name that appears in the From field. In case that's not true we could reject legitimate email.

Difficult to say. :-/

Agreed.
