Fixing “CyberPanel can’t send email”

When we have the problem “CyberPanel can’t send email,” it signifies that the server is having trouble sending mail to the control panel. There are numerous possible causes for this issue:

1. The setup of CyberPanel must be correct with the right SMTP settings in order to send emails. So we must make sure the SMTP server IP, port number, and authentication information (username and password) are accurate.

2. Check any firewall rules or port-blocking configurations that are preventing CyberPanel from creating outgoing connections to the SMTP server. Also, verify that the required SMTP ports are open (often port 25 for unencrypted SMTP or port 587 for encrypted SMTP).

3. Check to see if the SMTP service we’re using is operational if it says “SMTP service unavailable.” Then check to see if the external SMTP provider we are using is operating normally and if there are any problems.

4. Make sure the setup and authentication of the email account we use to send email is correct. Specific SSL/TLS encryption is required by some SMTP servers.

5. Verify that the DNS settings on the server are accurate and that the MX (Mail Exchange) records for the domain are set up to point to the appropriate mail server.

6. CyberPanel has a mail queue where incoming emails, before sending, will stop momentarily. Emails may not be sent if the mail queue is experiencing problems. Look for any mail queue-related error messages.

7. A server with insufficient disk space may also have problems sending emails. In order to verify that the server has sufficient free disk space to support email-sending operations.

8. When there are problems with the email’s content (such as huge attachments) or the recipient’s email address is wrong or unreachable, emails may occasionally fail to transmit. So check with it.

We can start by looking for any mail-related error messages in the logs to help us fix the problem. These logs can also offer useful details regarding the origin of the issue. Also, make sure all settings are accurate and double-check the email configuration.
