For a project I had to go to a hospital somewhere in the Netherlands. In the hospital their was someone who was committing fraud and we have to investigate it. One of the data-sets we requested was the mailbox of the suspect person. Usually I have to deal with M$ Exchange server
, but now I was very happy… they use the SUN Internet Mailserver from SUN Microsystems
This mail-server is not supported anymore by SUN… but that is not the topic of this post… the mail-server stores it mail in the Maildir way… 
A lot of my collegues didn’t even now that their was another way of storing e-mail besides the Exchange or Lotus Notes way. 
So I had to explain the difference between a Maildir and a mbox.
