As I am also using an *.eu.org domain, I strongly suggest using the DMARC record for your domain. I think the DMARC record for the whole eu.org domain is a mistake by the domain maintainers, because eu.org is a publicly available suffix, kinda like a TLD, and having DMARC record on eu.org is similar to having a DMARC record on the top-level .com domain for example. The various xxx.eu.org domains belong to different entities so they should not be processed under a common "umbrella". Use DMARC for your own domain to clearly signal that your xxx.eu.org domain and the parent eu.,org domain are NOT the same entity. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ Postfix-users mailing list -- postfix-users@postfix.org To unsubscribe send an email to postfix-users-le...@postfix.org
