Hello :) It's possible the remote mail servers are blocking connection attempts from the cPanel server. Try running the following command from the cPanel server to verify if that's the case: telnet remote-mail-server.tld 25
Is the connection refused? Note that you should also ensure your server meets the guidelines described in this document: How to Keep your Email out of the Spam Folder - cPanel Knowledge Base - cPanel Documentation Thank you.0 -

Hello, I disabled my csf and the results are the same. Thank you. 0 -
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. 0 -
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. 0 -

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.0 -

I am happy to see the issue is now addressed. Thank you for updating us with the outcome. 0
