DMARC: Our data indicates MBS Books supports DMARC compliance via SPF.
DKIM: Contact MBS to ask about their DKIM capabilities.
SPF: All traffic we've seem comes from 'mbssmtp.mbsbooks.com' which translates into an addition of 'ip4:188.8.131.52' to your SPF record. In any case, be sure to contact MBS and verify this information before making changes to your SPF.
