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:Demarc@onmicrosoft.com; ruf=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:Demarc@onmicrosoft.com; ruf=mailto:Demarc_forensic@onmicrosoft.com; fo=1:d:s

It'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
See 554 5.7.5 permanent error evaluating dmarc policy for the complete answer.

@Pawel Gieraltowski @danden123 is right. You've to also make you've warmed up your email reputation via an email warmup service. Otherwise, if you don't email warm up chances of running into 554 5.7.5 is high especially if your domain is new.
