dovecot-imap configuration error?
 

I want to setup the dovecot-imap in debian wheezy. i use the mail box "/var/mail/david and this is the file "/etc/dovecot/conf.d/10-mail.conf" i configured for the inbox:

The dovecot cannot get the mail box (mbox), this is the "/var/log/mail.err" error:

I'm no linux master, but it sounds to me like the process that writes /var/log/mail.error -- i assume this is Dovecot -- lacks the necessary file system permissions to write either /home/david/Mails or /var/mail/david. They provide a link. Did you read it?
