[Dovecot] Conf problems ??

Hello,

I am having problems with configuring dovecit. The imap directory was correctly made in ~/mail/.imap

But I can't see any mail headers. My mbox path is ~/mail/incoming

Currently I am trying to use "mbox:~/mail/:INBOX=~/mail/incoming" for configuration but it complains about missing value. Can someone send me more information on configuration directives especially mbox and INBOX.

Early reply shall be appreciated.

Regards, Mahesh
