Error 554 5.7.5 Permanent error evaluating DMARC policy
Recently ran into this error when sending email from our domain.
Could not find much help about this error so posting my solution as a reference.
What ended being a problem is DMARC recodrd in DNS
Our record was:
v=DMARC1; p=none; rua=mailto:mailto:Demarc@onmicrosoft.com; ruf=mailto:mailto:Demarc_forensic@onmicrosoft.com; fo=1:d:s.
The problem was period(dot) at the end of the record, after removing period and DNS repopulated, everything worked!
Corrected record:
v=DMARC1; p=none; rua=mailto:mailto:Demarc@onmicrosoft.com; ruf=mailto:mailto:Demarc_forensic@onmicrosoft.com; fo=1:d:s

Pawel_Gieraltowski @danden123 is right. You've to also make you've warmed up your email reputation via an https://emailwarmup.com/ service. Otherwise, if you don't https://emailwarmup.com/ chances of running into 554 5.7.5 is high especially if your domain is new. You can also talk to an https://emaildeliverabilityconsultant.com/ if you're still unsure what to do.
JohnSen685 I absolutely agree and Thank You for for this.

AdamIt's got to be one of them.
1. Unnecessary Characters from Your DNS record
2. Your SPF should be set to Neutral
3. Verify if your Email Service Provider (ESP) enables SPF Alignment
4. Adjust the DMARC policy to “p=none”
5. Set up DKIM Authentication
