Mailfence email authentication

Belgian privacy-focused mailbox provider.

SPF record

Add Mailfence to your domain's SPF record with this include:

include:_spf.mailfence.com

A complete record for a domain sending only through Mailfence:

v=spf1 include:_spf.mailfence.com ~all

What it costs you

1 of your 10 DNS lookups. That is the cheapest an include can be — the record it points at contains only IP ranges, with no further includes to follow. Behind it are 2 IP ranges.

Live record

This is what _spf.mailfence.com published when this page was generated:

v=spf1 ip4:212.3.242.64/26 ip4:217.182.28.163 ~all

DKIM

Enable DKIM inside Mailfence and publish the selector record it generates. DKIM matters more than SPF for deliverability, because a DKIM signature survives forwarding while SPF does not — see how selectors work.

DMARC

Neither SPF nor DKIM protects the address your recipients actually see until DMARC ties them to it. Once Mailfence is authenticating, publish a DMARC record — start at p=none with a reporting address and tighten from there.

Check it worked

DNS changes take minutes to hours to propagate. Once published, run the domain through the checker — it resolves the full include chain and reports the real lookup count.
