I need to enhance the sender reputation of emails for business transactions and it does seem with mail-tester and other platforms for testing email deliverability that 1024 key length needs to be upgraded to 2048 to pass testing. Not sure if this does enhance deliverability but if more than one testing platform suggests the DMARC/DKIM testing is failing then perhaps we need to consider this?
