#
# == Class: postfix::satellite
#
# This class configures all local email (cron, mdadm, etc) to be forwarded
# to $root_mail_recipient, using $postfix_relayhost as a relay.
#
# $valid_fqdn can be set to override $fqdn in the case where the FQDN is
# not recognized as valid by the destination server.
#
# Parameters:
# - *valid_fqdn*
# - every global variable which works for class "postfix" will work here.
#
# Example usage:
#
#   node "toto.local.lan" {
#     class { 'postfix::satellite':
#       relayhost           => "mail.example.com"
#       valid_fqdn          => "toto.example.com"
#       root_mail_recipient => "the.sysadmin@example.com"
#     }
#   }
#
