Hey Yeo, tldr; smtp11.infineon.com. IN TXT "v=spf1 a -all" Add this to each mta, all mta's should have A, AAAA, and SPF like the one above.
The spf "a" mechanism is for all host entries (so both v4/v6) (see http://www.openspf.org/SPF_Record_Syntax#a) Thanks, -Jake From: "dmarc-discuss" <dmarc-discuss@dmarc.org> To: "dmarc-discuss" <dmarc-discuss@dmarc.org> Sent: Sunday, June 4, 2017 11:09:20 PM Subject: [dmarc-discuss] OOF failed DMARC verification by linkedin Hi all, We just recently enabled DMARC for our outgoing mails. We noticed our out of office (OOF) messages to internet so far ok e.g gmail.com. But when OOF messages send to linkedin.com we will get DMARC verification failed due to Original-Mail-From is blank. How to overcome such issue as a sender? Thanks.
