I have workflows that will fire a few emails. Till 6 hours back, all the emails were firing perfectly. Now, only emails of selective workflows are firing. When I checked the email log, the emails that were not fired had the Mail Event as P (Permanent Failure). What is the cause for this? I have not changed my email id or the workflow rules.

Update:

550-5.7.1 Unauthenticated email from yahoo.com is not accepted due to domain's\r\n550-5.7.1 DMARC policy. Please contact administrator of yahoo.com domain if\r\n550-5.7.1 this was a legitimate mail.

554 5.7.9 Message not accepted for policy reasons.  See https://help.yahoo.com/kb/postmaster/SLN7253.html

These are 2 errors present in the Email Log

  • Did you check email deliverability setting in setup? It should be set to "All email"

As per the given message:-

Unauthenticated email from yahoo.com is not accepted due to domain's\r\n550-5.7.1 DMARC policy. Please contact administrator of yahoo.com domain if\r\n550-5.7.1 this was a legitimate mail.

You will not be able to send message from the domain name yahoo.com. The only solution would be is change the sender's (from) email Id to other domain like gmail etc.

  • Their DMARC policy doesn't allow receive email having/missing particular attributes. Its all yahoo server's configuration which is not allowing email. @User2529
