1. IP BLACKLISTED
The most common problem that mails you send do not arrive is because the IP of the server running Cpanel's Webmail has been blacklisted. You can check here whether the IP actually appears on blacklists. If so, you can contact the blacklist and request delisting. If this does not work, it is best to ask the company from which you lease a server or VPS if they can arrange this for you. They have much more power than you.
2. SSL/TLS Settings
When using a mailclient like Thunderbird or Outlook you should verify that your SSL/TLS Settings you are using are correct. Most important in this case is to use port 465 for outgoing mailserver. You'll find all the correct settings by logging in to your Cpanel. Then go to "Mail accounts". To the right of your accounts click on "Connect devices". Settings are there listed.
3. RESTART PC/LAPTOP
Restart your device. To troubleshoot your computer, restart it if your computer hasn’t been turned on in a while. This will erase your computer's internal memories (RAM) and may resolve many issues.
4. USE DIFFERENT BROWSER
A browser that isn't compatible or out of date can cause Cpanel to stop sending emails. If you are using an older or incompatible browser, Cpanel Webmail can still be accessed via another browser. You will need to install or update a supported browser if you don't have one installed.
5. CLEAR BROWSER CACHE
Clearing your browser cache is a crucial step in solving web problems. This is a soft reset. It removes temporary files from your browser and allows you to replace them as needed. It is hoped that the browser will eventually repair itself. In Chrome, this can be done by clicking on the More menu (three vertical dots at the top of the browser) > More tools > Clear browsing history.
6. DISABLE FIREWALL
A firewall prevents hackers from accessing your computer via the internet and infecting it with malware. It should always be on. If you have to diagnose Cpanel not sending mails, it is possible to temporarily disable the firewall.
7. DISABLING PROTECTED MODE IN IE
Internet Explorer's version anti-virus program is Internet Explorer's protection mode. It stops malicious software from taking root on your computer. It can cause webmail and other browser applications to stop functioning, so it is worth deactivating it. Open Internet Explorer's "Tools" menu and click on the "Advanced tab. Deactivate "Enable enhanced protected mode".
