How to Interpret SMTP Server Logs?

Interpreting SMTP server logs requires understanding the status codes and error messages. Common status codes include:
250: Email successfully delivered.
550: Delivery failed due to a non-existent email address.
450: Delivery temporarily failed, usually due to a full mailbox.
421: Service temporarily unavailable.
By analyzing these codes, you can diagnose and troubleshoot delivery issues effectively.
