Add email footer to all send out emails

[brotherbui]

Hi everyone,

Could you tell me how to add footer to all emails that will be sent out by vBulletin?

For example, here is the original one:

Hello boogle,

We at vBulletin.org would like to wish you a happy birthday today!

And what I'm looking for is something like this:

Hello boogle,

We at vBulletin.org would like to wish you a happy birthday today!

------------------------------------------
This is the footer that will appear in all emails

Thanks
