Strange Email Issue
A former employee is sending email from his new employer's email account to his home account, but the email is ending up being delivered to his former employer's email server, where it is refused (no such account since he left).
The user has already checked his personal account to confirm it is not configured to forward to the old-employer's account. The user's personal account ISP has checked settings as well.
mx2.zoneedit.com is the back-up email server for the receiving domain.
