mail-forwarding

I would like to implement some kind of filter to add a disclaimer message within emails forwarded to outside domains.

Today we have some users that setup filters to forward messages to external mail servers, as example @gmail addresses. So this kind of forward should be marked with the disclaimer message. Not the normal fwd messages.

We have a Postfix mailfiltering gateway too, if it's simpler to implement this on the mail filter, it could be a viable option.

What would be the best approach to handle this issue?

Thanks,
