E-mails from O2 fail DMARC.

RokeJulianLockh — Thu, 24 Aug 2023 14:40:25 GMT

O2's messages sent via e-mail are failing DMARC validation.

https://github.com/anonaddy/anonaddy/discussions/507#discussioncomment-6813832

The DMARC check has failed dmarc=fail because the SPF and DKIM domains are not aligned. o2.com is not the same as or a subdomain of o2mail.co.uk.

Nobody here can change this, @RokeJulianLockh - reach out to O2 via social media at the link just below this post.

@RokeJulianLockh

I have had a look at all 3 email I got from o2mail.co.uk this week, and only 1 has failed SPF, this happens in enterprises switch DNS and SPF records and mail services just deal with it, not sure why AnonAddy hasn't.

And none are failing any DMARC or DKIM checks on my own mailservers..

SPF is fine

DMARC is fine :

Full DMARC record

v=DMARC1; p=none; rua=mailto:dmarc-rua@o2mail.co.uk

Can you post the full message header and not just the bit you posted on the Anonaddy git site...

Indeed, I understand that users like myself cannot modify their mail servers. I reported this here in addition to at GitHub because if an employee were to want to respond via here instead of e-mail (for I am somewhat misusing their complaints address) it would be less difficult for them.

Re: E-mails from O2 fail DMARC.

@RokeJulianLockh

I just need the headers not the source as well.

The only thing that email fails on is DKIM Hash, which is about part of the course with DKIM signatures.. So in my professional opinion,

Also it is not brilliant that AnonAddy in the headers shows your mail provider aka M365, I would expect a tool that anonymises email addresses to change the recipient mail servers as well..
