Our server has apparently lost some email. The company's client says that 2 emails were supposed to have been received and I looked through /var/log/mail.log*
files by using zgrep and the two emails turned up. However, when I searched through the mailbox, only one of the emails was there. The client has assured me that he didn't accidentally delete the 2nd email, but I have no idea where it could have gone.
Are there any other log files that I can check or has the client simply forgotten that he deleted the email (PEBKAC)
