 * `URL` is the url to post the parsed email to. The url can contain basic auth credentials. Example:  `https://user:password@requestb.in/1bcv6631`
 
+* `__MAX_EMAIL_SIZE__` Allows you to modify the maximum size of an email. The default value is 1000000 for a 1MB email.
+
 * The email is parsed to JSON and posted to the webhook. You can find an [example JSON body here](https://github.com/thingless/mailglove/blob/master/example_post_body.json).
