I have tested and there is still an issue with mysql because I get the 
following error :

Aug 07 12:51:20 auth: Fatal: Unknown passdb driver 'mysql'
Aug 07 12:51:20 master: Error: service(auth): command startup failed, 
throttling

I am sure that mysql is installed and I have also installed 
dovecot-mysql_2.0.13-0~auto+70_i386.deb
