This means that you start deliver as vmail:vmail (which I guess is  
intended), but userdb lookup says that this user should have GID  
paranoidandroid. So deliver tries to change the proces's GID, but  
isn't allowed to because it's not running as root.

What do you have in user_query? Is it intended that different users  
have different gids (and maybe uids)?
