Hi am sending Prestashop email via /usr/sbin/sendmail in Prestashop v 1.7.8.7
Have set up DKIM records /keys on server DNS _domainkey.domain.co.uk & default._domainkey.domain.co.uk also DMARC record with_dmarc.domain.co.uk
DMARC works, but repeatedly fails on DKIM when testing. Is there a solution to this - I also have an older 1.6 site setup that has been set up with similar settings above and DKIM works perfectly there. Anyone help? Thanks
