Fix my email sending issue with MailWizz


I need someone with strong skills with DNS and MailWizz newsletter sending application.

Here is my issue:

I have a MailWizz installation on DigitalOcean to send newsletters. I'm also using my domain with Zoho mail. I'm also using an SMTP delivery service.

My problem is that some of my emails are not delivered to certain email service providers, like [login to view URL], or [login to view URL]

I'm getting errors like this:

This is the mail system at host
