Franck,

What if the RFC7208.MAILFROM is empty?  I recall some questions from colleagues 
re dmarc reporting and the spf scope (help or mailfrom).

Thanks,

Dave

Subject: Re: [dmarc-discuss] Multiple SPF results in report

It is a bug.

There can only be one SPF per record. Theoretically SPF returns 2 results, one 
for the RFC7208.HELO and another one for RFC7208.MAILFROM, but DMARC takes as 
input only RFC7208.MAILFROM, therefore only this results is needed in DMARC 
reports.

RFC7208.MAILFROM is not RFC5321.MailFrom, there is a subtle but important 
difference here.

Do you mean that in the XML you see 6 <spf> elements in one <auth_results> 
element? Or do you mean you see 6 different <spf> domains in the your reports?

I received a DMARC report with multiple SPF results. I wonder how this is 
possible as I only have one SPF record for my domain defined. In one report I 
got 6 SPF results.

The only thing I could think of is some automatic forwarding service changing 
the return path header. Are there more usecases possible how this can happen?

Thanks
Nick
