Can a disclaimer be added to all outgoing mail?

Question

Can a disclaimer be added to all outgoing mail?

Answer

cPanel doesn't natively support adding content of any type to outgoing emails. However, you can use a transport filter hook to run a script that will add a disclaimer to each outgoing email. Exim provides a brief overview of using this hook in the following article.

Please note that cPanel support cannot assist with creating the hook or the script called by the hook.
