'DMARC validation failed' mail delivery errors

Hi, 

Can anyone help me with a 'DMARC validation failed' mail delivery errors please? 

Our email set-up is a little bit complicated. We have a domain, email and webhosting with another provider, but the mailboxes are very small (only 2 GB). So we have set-up email aliases and forward our emails to our virgin media email address, as the mailbox accounts are larger. Unfortunately in recent months we have been getting lots of emails rejected and a bounce back (Mail delivery failed: returning message to sender) to our provider from Virgin media for ‘DMARC validation failed’. Is there anything I can do to stop this and get my emails through? I’ve added some of the email addresses to my address book on virgin media, but that hadn’t resolved this issue. We have a DMARC policy set against our domain, which I’m told is correct.

This is an example

 

This message was created automatically by mail delivery software.

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error.

The following address failed:

 

  [MOD EDIT: Email address removed]

        SMTP error from remote server for TEXT command, host: hostname.net (IP address) reason: 554 5.2.0 MXIN603 DMARC validation failed. ;id=6TapoS1QdxIyN6TaqoAXot;sid=

6TapoS1QdxIyN;mta=mx8.tb;dt=2022-06-29T11:02:41+02:00;ipsrc=IP address;

 

 

Many thanks.
