Are you getting errors when trying to start exim/dovecot manually?  If 
so, are the configuration files on the drbd device (because of HA 
requirements)?  And if so, create the configuration files elsewhere and 
make sure exim/dovecot are looking for those configuration files in that 

Hope that's what you're looking for.
