+ # In order to send mail, Arvados expects a default SMTP server
+ # on localhost:25. It cannot require authentication on
+ # connections from localhost. That server should be configured
+ # to relay mail to a "real" SMTP server that is able to send
+ # email on behalf of your domain.
+
+ # See also the "Users" configuration section for additional
+ # email-related options.
+
+ # When a user has been set up (meaning they are able to log in)
+ # they will receive an email using the template specified
+ # earlier in Users.UserSetupMailText
