[[:nickname]]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624

A new feature to send a message to the sender of the currently selected
messages, faking a mailer-daemon delivery status message.

This is a convinient way to try to let the sender know that the mailbox is not
avialable (although it is).

Thoughts:
The feature would reside in the menu "Message" as "Reject". Upon activating, it
will start up the composer with:
1. a pre-made delivary-status message (multipart/report with text/plain,
message/delivery-status and text/rfc822-headers parts)
2. the the To: field filled out with the return path

The content of the message would be any like the popular sendmail default
message, like

"The original message was received at <date of the received message> from
mail.xyz.com

 ---- The following addresses permanent fatal errors ----
[e-mail]

 ---- Transcript of session follows ----
myaccount: Mailbox does not exist
550 <[e-mail]>... User unknown"

This part should be from a template, a default one like this shipped with
mozilla; but exchangeable by the user (just like signatures). The other parts
should be reassembled to make the remote end think this user is what the
messages says: unknown.

Reproducible: Always
