+## mailer
+
+The following three configuration variables must be set if you want mailer to use remote SMTP settings:
+
+    smtp_address - defaults to "localhost"
+    smtp_port - defaults to "25"
+    smtp_domain - defaults to "localhost.localdomain"
+
+There is an optional subscriptions hash which can be added to your mailer.json file.  This subscriptions hash allows you to define individual mail_to addresses for a given subscription.  When the mailer handler runs it will check the clients subscriptions and build a mail_to string with the default mailer.mail_to address as well as any subscriptions the client subscribes to where a mail_to address is found.  There can be N number of hashes inside of subscriptions but the key for a given hash inside of subscriptions must match a subscription name. 
+
+```json
+{
+  "mailer": {
+    "mail_from": "sensu@example.com",
+    "mail_to": "monitor@example.com",
+    "smtp_address": "smtp.example.org",
