[Dovecot] mail directory in user home?

Hey:

When I run dovecot and retrieve any mail for a user, a mail directory is created in the users home. It has a subdirectory Inbox. No mail goes there however, it all goes to /var/spool/username. What is that directory for and how do I get it to not make it or can I? I am only using POP3.

Thanks,
