I get DMARC reports sent from various different sources. All of the reports generally have <result>pass</result> for all of the sections.

However, the reports from Google always have SPF fails:


My SPF record looks like:

"v=spf1 +a +mx +a:server.domain.co.uk include:email-od.com ~all"

I am unsure why my bounce domain is failing SPF checks, but it only seems to be on Google DMARC reports.

To be honest, I am unsure what the bounce domain bounce.domain.co.uk does, should I set up an email address [email protected]?

Any help sorting my SPF and advice regarding bounce.domain.co.uk would be great.

bounce.domain.co.uk should have an SPF record in order to pass authentication check and header from domain should be equal or aligned with bounce.domain.co.uk in order to pass DMARC check

  • Thanks for your answer. Should bounce.domain.co.uk not be covered in the SPF that i have, in particular this section "v=spf1 +a +mx +a:server.domain.co.uk

  • The IP address, from which bounce.domain.co.uk sends, need to covered by that spf record. You can use any spf lookup tool, e.g. easydmarc.com/tools to check of sending IP is there
