Error 554 5.7.5 Permanent error evaluating DMARC policy

Copper Contributor

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;;; 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;;; fo=1:d:s

Thank you for this!



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
