#
# == Class: postfix::mta
#
# This class configures a minimal MTA, listening on
# $postfix_smtp_listen (default to localhost) and delivering mail to
# $postfix_mydestination (default to $fqdn).
#
# A valid relay host is required ($postfix_relayhost) for outbound email.
#
# transport & virtual maps get configured and can be populated with
# postfix::transport and postfix::virtual
#
# Parameters:
# - *$postfix_relayhost*
# - *$postfix_mydestination*
# - every global variable which works for class 'postfix' will work here.
#
# Example usage:
#
#   node 'toto.example.com' {
#     $postfix_relayhost = 'mail.example.com'
#     $postfix_smtp_listen = '0.0.0.0'
#     $postfix_mydestination = '$myorigin, myapp.example.com'
#
#     include postfix::mta
#
#     postfix::transport { 'myapp.example.com':
#       ensure => present,
#       destination => 'local:',
#     }
#   }
#
