Mail cannot send message process exited with a non zero status

The infamous "process exited with a non-zero status" error!

This error typically occurs when your email client or server is unable to send an email message, and the process that handles the sending of the email exits with a non-zero status code, indicating that an error occurred.

Here are some common causes and solutions to help you resolve this issue:

  1. Network connectivity issues: Check your internet connection and ensure that you are connected to a stable network.
  2. Email server issues: Verify that your email server is functioning correctly and that you have the correct server settings. You can try sending an email using a different email client or server to isolate the issue.
  3. Email client configuration issues: Check your email client's configuration settings, such as the SMTP server, port, and authentication settings. Make sure they are correct and match your email provider's settings.
  4. Outdated email client: Ensure that your email client is up-to-date and compatible with your email provider's servers.
  5. Firewall or antivirus software issues: Firewalls or antivirus software may be blocking the email client's ability to send emails. Try temporarily disabling these programs to see if it resolves the issue.
  6. Email provider issues: Check your email provider's status page to see if there are any known issues or outages affecting email sending.
  7. Message size or content issues: If you're sending a large attachment or a message with a specific content, it may be causing the issue. Try sending a smaller message or attachment to see if it resolves the issue.
  8. Email client plugins or add-ons: Disable any plugins or add-ons you have installed in your email client to see if they are causing the issue.

To troubleshoot the issue, you can try the following:

  1. Check the email client's error logs or debug logs to see if they provide any additional information about the error.
  2. Use a tool like telnet or nslookup to test your email server connection and verify that you can connect to the server.
  3. Try sending an email using a different email client or server to isolate the issue.
  4. Contact your email provider's support team for assistance, as they may be able to provide more specific guidance or troubleshooting steps.

I hope these suggestions help you resolve the "process exited with a non-zero status" error and get your email sending working again!
