The simplest way to set up a mail server is through the Confluence Administration console. See Configuring a Server for Outgoing Mail.

If you want to add different options or parameters you can also set up a mail session for the Confluence distribution. In the example below we'll set up Gmail.

To set up a mail session for the Confluence distribution:

  1. Stop Confluence.
  2. Move (don't copy) the following files from <confluence-install>\confluence\WEB-INF\lib to <confluence-install>\lib

    jakarta.mail-x.x.x.jar
    javax.activation-x.x.x.jar
    javax.activation-api-1.2.0.jar

    (x.x.x. represents the version numbers on the jar files in your installation)

    Don't leave a renamed backup of the jar files in \confluence\WEB-INF\lib. Even with a different file name, the files will still be loaded as long as it remains in the directory.
  3. Edit the <confluence-install>\conf\server.xml file and add the following at the end of the Confluence <context> tag, just before </Context>.
    Note: you're editing the <context> tag that contains the Confluence context path, not the one that contains the Synchrony context path.

    <Resource name="mail/GmailSMTPServer"
        auth="Container"
        type="javax.mail.Session"
        mail.smtp.host="smtp.gmail.com"
        mail.smtp.port="465"
        mail.smtp.auth="true"
        mail.smtp.user="yourEmailAddress@gmail.com"
        password="yourPassword"
        mail.smtp.starttls.enable="true"
        mail.transport.protocol="smtps"
        mail.smtp.socketFactory.class="javax.net.ssl.SSLSocketFactory"
    />
    
  4. Restart Confluence.
  5. Go to  > General Configuration > Mail Servers.

  6. Select either Edit an existing configuration, or Add a new SMTP mail server.
  7. Edit the server settings as necessary, and set the JNDI Location as:

     java:comp/env/mail/GmailSMTPServer
    


    Note that the JNDI Location is case sensitive and must match the resource name specified in server.xml.

  8. Save your changes and send a test email.
