# # Set the suffix of the email address that will be automatically generated
# for a user that does not have an email address. This property is not used
# unless the property "users.email.address.required" is set to false. The
 # autogenerated email address will be the user id plus the specified suffix.

# com.liferay.portal.security.auth.EmailAddressGenerator. This class will be
# called to generate an email address for a user that does not specify an
# email address. This class will only be used if the property
# "users.email.address.required" is set to false.
