Adding text on bottom of mail

[Necrotic]

What file do I edit and where in the file do I edit to ad a string of text within the mail box homepage? I know I seen it posted here before but can't seem to find it now.:cool:

/skins//templates/mail.html

Or make a plugin, so you dont have to edit this every time you install a new version.
