How can I check an email against its dmarc signature ? ie, check that the dmarc signature associated with the email is VALID.
I am a Ubuntu user, I am aware of the dkimpy package allowing this for dkim (dkimverify < email.eml) and ideally would like to do a simple dmarcverify < email.eml or similar functionality, to check the DMARC (not dkim) signature is valid.
Google search has not led me anywhere (or I missed the point maybe... i am not expert in that area).
Thanks. Christophe
