Let the user use the client s/he was using just moment the messages 
disappeared.

Disable POP3. ;-)

Anyway, to identify such problems I recommend using the mail_log plugin. 
It uses resources (slows down server, consumes logging space), but you 
can see _when_ the INBOX got empty and I will bet that most of the time 
the last access was via POP3. It might happen that an user 
unintentionally delete the INBOX, which is automatically recreated later.
