[imp] Where does imp get it's mail preferences from?

[Eric A. Bonney]

I am trying to iron out a few remaining bugs with my email setup. I am  
using exim4 and dovecot and attempting to implement a system where  
mail users will not have actual accounts on the server.

I have exim4 and dovecot mostly working properly at this point, but  
when I login to IMP, it doesn't see any mail even though there are new  
messages on the server.

So how does IMP know where to look for the mail? On the new system all  
mailboxes are going to be stored on a centrally located drive like this:

/MailBoxes/domain/user

Both dovecot and exim4 have been properly configured (at least I think  
so) and they are delivering new mail properly, but I think I need to  
set something in IMP to see the mail. I have looked in the servers.php  
but that is only specifing the IMAP server connection. Is this  
something that is supposed to be taking care of by dovecot? If so then  
I at least have it narrowed down to where to start looking. :)

Thanks,
