Jenkins Email notifications not sent.

What is Jenkins Email notifications not sent.

Understanding Jenkins

Jenkins is an open-source automation server that enables developers to build, test, and deploy their software reliably. It is a popular tool for continuous integration and continuous delivery (CI/CD) pipelines, allowing teams to automate various stages of their development process.

Identifying the Symptom

One common issue that Jenkins users may encounter is the failure of email notifications to be sent. This symptom is typically observed when build or job notifications are expected but not received by the intended recipients.

Exploring the Issue: JENKINS-417

The issue identified as JENKINS-417 relates to email notifications not being sent from Jenkins. This can be a critical problem, especially for teams that rely on email alerts to stay informed about build statuses and other important events.

Root Cause Analysis

The root cause of this issue often lies in misconfigured email server settings or incorrect Jenkins email notification settings. It is crucial to ensure that Jenkins is properly configured to communicate with the email server.

Steps to Resolve the Issue

Step 1: Verify Email Server Configurations

First, check the email server configurations in Jenkins. Navigate to Manage Jenkins > Configure System and locate the Email Notification section. Ensure that the SMTP server details, including the server address and port, are correctly entered.

SMTP Server: smtp.example.com SMTP Port: 587 (or the port used by your server)

Step 2: Check Credentials

Ensure that the credentials used for the email server are correct. This includes the username and password required for authentication. If your email server requires SSL or TLS, make sure these options are enabled.

Step 3: Test Email Configuration

Jenkins provides a way to test the email configuration. In the Email Notification section, use the Test configuration by sending test e-mail button to send a test email. Check if the email is received successfully.

Step 4: Review Jenkins Email Notification Settings

Ensure that the email notification settings are correctly configured in your Jenkins jobs. This includes specifying the recipients and ensuring that the Post-build Actions section includes the Email Notification option.
