Translation template import mails should have a rationale message at the bottom

[Māris Fogels]

The "Translation template import" mails sent by Launchpad should have a rationale message at the bottom stating why I got the mail, and how I can shut it off.

Rationale messages also make text-based filtering in Gmail easier. Necessary because Gmail can not filter on custom headers.

Here is the text of a template import message I received today:

{{{
Subject: Translation template import - rhythmbox-ubuntuone-music-store in The
 Ubuntu Music Store Rhythmbox plugin trunk

Hello Ubuntu One,

On 2010-03-03 10:50z (3 minutes ago), you uploaded a translation
template for rhythmbox-ubuntuone-music-store in The Ubuntu Music Store
Rhythmbox plugin trunk in Launchpad.

The template has now been imported successfully.

Thank you,

The Launchpad team

FWIW, you can't shut it off other than by not uploading templates :)

This email doesn't even have proper special headers, so it'd be nice to add these as well.

see also bug 855150 asking for them to just be shut off.
