Apache james not sending mail

Apache James is a Java-based email server that can be used to send and receive emails. If Apache James is not sending mail, there could be several reasons for this issue. Here are some common causes and solutions:

  1. Check the Apache James logs: The first step is to check the Apache James logs to see if there are any error messages that could indicate the cause of the issue. You can find the logs in the logs directory of your Apache James installation.

  2. Check the email configuration: Make sure that the email configuration is correct in the james.properties file. Check that the mail.smtp.host and mail.smtp.port properties are set correctly.

  3. Check the mail server connection: Make sure that the mail server is running and that the connection to the mail server is working correctly. You can use a tool like telnet to test the connection to the mail server.

  4. Check the email account credentials: Make sure that the email account credentials are correct and that the account is active.

  5. Check the Apache James configuration: Make sure that the Apache James configuration is correct and that the email sending feature is enabled.

  6. Check the Java version: Make sure that you are using a compatible version of Java with Apache James.

  7. Check the Apache James plugins: Make sure that the Apache James plugins are installed and configured correctly.

Here is an example of how to configure Apache James to send an email:

# james.properties
mail.smtp.host=smtp.gmail.com
mail.smtp.port=587
mail.smtp.auth=true
mail.smtp.starttls.enable=true
mail.smtp.starttls.required=true

You can also use the Apache James web interface to configure the email settings.

If you are still having issues with Apache James not sending mail, you can try enabling debug logging to get more information about the issue. You can do this by setting the log4j.rootLogger property to DEBUG in the log4j.properties file.
