Divorce proceedings are prone to getting nasty, and Paula and Barry Epstein's divorce appears to be no exception. Paula accused Barry of "serial infidelity," and when Barry's attorney demanded proof, Paula's lawyer turned over dozens of emails from Barry to several women not named Paula Epstein. Believing that Paula must've been forwarding his emails to her address, he sued her (and her attorney) under the federal Wiretapping and Electronic Surveillance Act.
And according to the 7th U.S. Circuit Court of Appeals, auto-forwarding your husband's emails to your address might violate the federal Wiretap Act even if "Congress probably didn't anticipate its use as a tactical weapon in a divorce proceeding."
