org.apache.james.transport.mailets.DSNBounce

All Implemented Interfaces:

org.apache.mailet.Mailet, org.apache.mailet.MailetConfig

public class DSNBounce
extends AbstractNotify

Generates a Delivery Status Notification (DSN) Note that this is different than a mail-client's reply, which would use the Reply-To or From header.

Bounced messages are attached in their entirety (headers and content) and the resulting MIME part type is "message/rfc822".
The reverse-path and the Return-Path header of the response is set to "null" ("<>"), meaning that no reply should be sent.

A sender of the notification message can optionally be specified. If one is not specified, the postmaster's address will be used.

Supports the passThrough init parameter (true if missing).

Sample configuration:

 
 <mailet match="All" class="DSNBounce">
   <sender>an address or postmaster or sender or unaltered, 
  default=postmaster</sender>
   <prefix>optional subject prefix prepended to the original 
  message</prefix>
   <attachment>message, heads or none, default=message</attachment>
   <messageString>the message sent in the bounce, the first occurrence of the pattern [machine] is replaced with the name of the executing machine, default=Hi. This is the James mail server at [machine] ... </messageString>
   <passThrough>true or false, default=true</passThrough>
   <debug>true or false, default=false</debug>
 </mailet>
