dont know about any dmarc problems with yahoo recently but using opendmarc with postfix is tricky look at the english links in https://sys4.de/de/blog/2014/09/20/fallstricke-mit-opendmarc-und-postfix/ please see differ in dmarc policy yahoo vs google _dmarc.gmail.com. 600 IN TXT "v=DMARC1\; p=none\; rua=mailto:mailauth-repo...@google.com"; _dmarc.yahoo.com. 1800 IN TXT "v=DMARC1\; p=reject\; sp=none\; pct=100\; rua=mailto:dmarc-yahoo-...@yahoo-inc.com, mailto:dmarc_y_...@yahoo.com\;"; specially p=reject vs p=none Best Regards MfG Robert Schetterer -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein
