I have been running several tests and all come back the same. The results show every test passing exceptionally well for example (SpamAssassin - Passed with a score of -0.1) but the ones below fail massively.

Does anyone have any advice or resources I could use to improve these scores?

Any assitance would be hugely appriciated.

TEST RESULTS THAT FAILED:
Microsoft Exchange Online Protection
Failed with a score of 9.0

GoDaddy

AOL Mail
