[Exim] Exim 3.34 - adding signitures to outgoing mail

Hi All

I have been asked to see if it is possible to automatically add a company
wide signature on all outgoing e-mail generated by our employees. i.e a
master "text" that is automatically appended to the bottom of all e-mail.

Ahh do it via MUA's I here you cry... well that is what I said. However
it was deemed that users would not update their personal signatures.

Anyway any help/pointers would be great.

Cheers

Jamie
