I know we have a whole community of smart guys here. So I'm posting a non poker related question.

Does anyone know if the larger ISP's keep logs of emails sent and received on their pop mail accounts?

I'm involved in a civil suit in which emails had been altered by someone and two copies, one altered and one legitimate exist.

Also is there any way to authenticate an email. Any way to tell a real from an altered?

I would really appreciate any feedback anyone may have on this.

Thank you all.
