That's probably a question for Microsoft to answer. :-) There is a _dmarc.outlook.hu TXT record: "v=DMARC1; p=none; rua=mailto:d...@rua.agari.com;ruf=mailto:d...@ruf.agari.com;fo=1:s:d"; but the policy is "none", so it doesn't matter if DMARC fails. A DMARC failure shouldn't result in any email being quarantined or rejected. A wierd thing is that their _dmarc record has "fo=1:s:d" which means that they want to receive reports for any DKIM failure. That would be every email that comes out of there. Maybe they are conducting a study on DMARC checkers. cheers, raf
