Softaculous Upgrades Email SMTP 554 failed authentication DMARC

So I don't use Softaculous. Before I get in to it: is this problem caused by a problem with the server configuration or Softaculous itself?

I received a couple error related emails in regards to Softaculous:

554 5.7.9 This mail has been blocked because it failed authentication checks against the sending domains DMARC policy. See https://senders.yahooinc.com/smtp-error-codes#dmarc-fail for more information.

The new host has had some problems with their initial configuration and it seems I've resolved most of those issues. However I don't know if this issue is caused specifically by Softaculous or the server configuration?

So, again, is this problem caused by a problem with the server configuration or Softaculous itself? Suggestions please?

  The SMTP configuration for your domain is not managed by Softaculous hence this doesn't look like a Softaculous issue.

  I agree - this doesn't have anything to do with Softaculous.
