Email green, secure, simple and ad-free - posteo.de -

“Posteo domain names used in the From header, in the envelope from/Return-Path header and for the signing DKIM domain (if DKIM-signed) are in strict aligment with each other. However, we have a DMARC “none” policy for Posteo email domain names, since DMARC is currently not recommended for mailbox providers. Outbound DMARC policies are primarily “best-suited for transactional emails and semi-transactional emails” (
dmarc.org
FAQ). At the present, DMARC has implications which do not meet customers’ individual use of email.”
Posteo is using DKIM not DMARC.
