mailbox in users' home directories

Hello 

I am a system administrator.  I am trying to incorporate procmail
and sendmail such that when mail arrives at my mail hub, procmail
would automatically kicks in to do the following:


1. instead of sendmail putting the mail in users' individual mailboxes
under /var/mail, I want procmail to intervene at this time, and put
the mail in the users' mailboxes in their home directories.

Thank you very much for your valueable help in advance.
