+# Many systems send emails "From" root@system-name. That causes problems when
+# an email is bounced. This type is used to have Postfix change the sender
+# address of an email while it is in flight. Both the From: header and the
+# envelope sender are changed.
+#
+# Example of how to set a sender:
+#
+# base::postfix::sender { 'root@stanford.edu':
+# ensure => 'noreply@stanford.edu'
+# }
+#
+# Example of how to ensure there is no sender map:
+#
+# base::postfix::sender { 'luke': ensure => absent }
+#
+# Assumes that a command 'postmap hash:$file' has been defined that will
+# rebuild the senders map.
+
+define base::postfix::sender(
+ $ensure,
+ $file = '/etc/postfix/senders'
+) {
+ $pattern = "'^${name}'"
+ case $ensure {
+ 'absent': {
+ exec { "rm-sender-${name}":
+ command => "sed -i -e '/^${name}/d' ${file}",
+ onlyif => "grep ${pattern} ${file}",
+ notify => Exec["postmap hash:${file}"]
+ }
+ }
+ default: {
+ $line = "${name} ${ensure}"
+ exec { "add-sender-${name}":
