Recently, I have been geeting a very peculiar problem regarding the mailbox of one user. Actually, as sysadmin, I checked for his stored messages in /var/spool/mail but could find messages for just last two days. There is no problem with the mailboxes of other users and even there is sufficient disk space on the mailserver(Red Hat 8.0). Actually, the user in question sometimes log in from different places and he told me that he is not using POP client.How can I track his lost messages ? Secondly, are there any log entries created somewhere when someone stores messages locally on the machine using POP client so that it can be used as a proof for arguement ?
Thanks alot in advance for co-operation
