It doesn't, because Dovecot starts them as root and then changes the  
privileges.

Maybe not alone, but this should work:

chmod 0777 /var/spool/mail
chmod +t /var/spool/mail

Or you could set mail_access_groups (or perhaps it's still called  
mail_extra_groups in your version) to "mail", assuming /var/spool/mail  
was owned by group mail and was group-writable.
