Yes but what does that mean? One can create and "backdate" (touch -t) any file. So how does one prove that an email is real and not created and backdated today?
If there is a copy of the purported Ceglia emails other than in Ceglia's imagination (e.g. in the verified forensic analysis previously done for the twins), then they truly do exist.
It would be interesting if a web email provider was used. Doubtful they have any decent retention strategies after you hit delete.
