Sonatype CLM Server - Installation And Configuration
The Sonatype CLM Server can be configured to send email notifications for events such as policy violations. This functionality requires an SMTP server available to the CLM server.
To allow the CLM server to send emails, you have to specify the
connection details to the SMTP server in the mail section of the
config.yml file displayed in Mail Configuration in config.yml.
Mail Configuration in config.yml. 
mail:
    hostname: your.mailserver.com
    port: 465
    username: user@company.com
    password: password
    tls: true
    ssl: true
    systemEmail: "SonatypeCLM@localhost"
      
The connection details are established with hostname and port and
optionally with the addition of username, password, tls and
ssl. The systemEmail parameter will be used as the sender email
for any emails the CLM server sends.
