    You can contact the remote mail servers individually to determine why they are blocking connections from your server (assuming the issue is isolated to specific remote mail servers). For example, with Yahoo:

    Helpcentral | SLN24439 - Yahoo Mail deliverability FAQs

    Ensure you are following the guidelines referenced in the document linked in my last response.

    Thank you.

    I have the exact same issue.

    The problem is like this, emails sent from Wordpress or WHCMS are sent via php mail. This does not work as designed alto the default WHCMS mail is info@example.ch the server sends the email from uhlhosting@panel.example.ch that what cause in a reject while the address is not present, or it the default email account.

    You may need to configure these applications to send email via SMTP authentication. For instance, WHMCS allows you to make this change in the configuration:

    Mail Tab - WHMCS Documentation

    Thank you.
