In eXo Platform, the registration page is disabled by default. If the registration page is enabled (see how-to), guests can register for eXo Platform by themselves. In this case, the administrators can configure the email service to be notified of the newly registered users, as follows:
Configure your SMTP server. You will need to configure your SMTP server correctly as described in Outgoing mail service.
Configure the service used for sending emails in portal.war/WEB-INF/conf/admin/admin-configuration.xml.
This file contains descriptions for each available parameter, including:
2 mandatory parameters:
sendMailAfterRegistration: Change this value to "true" (It is "false" by default so sending emails after registration is disabled).
mailTo: Add your email address here.
Optional configurations of mail content:
mailFrom: This will be used as from header in the mail.
mailSubject: The Subject (Title) of the mail.
mailMessage: The content of the mail.
Use the ${user.userName} token for mailSubject and mailMessage. For example, put this sentence: "${user.userName} has been registered!" in mailSubject. When the mail is sent, the token will be replaced with real username.
To check if your configuration takes effect, restart the server and register a new user. An email that notifies of newly registered user should be sent to you.
