550↑

550-SPF-check failed: 550 example.com doesn't allow sending mails from xx.xx.xx.xx (in reply to MAIL FROM command)

The sent message failed the SPF policy for the sending domain. To resolve this, you'll need to make sure the mail server you are sending mail from is in the sending domain's SPF record.

550 Message from example.com failed sender's DMARC policy, REJECT

The sent message failed the DMARC policy for the sending domain. If the sending domain has a reject policy set for DMARC, the message must pass DKIM or have SPF aligned to the domain with a custom Return-Path. To resolve this, you'll need to contact your email service provider to see how to configure SPF and/or DKIM properly.
