[imp] admin user and dovecot

[Michael Cramer]

Hello,

i've read in the backends.php that a master user can be configured for  
mailbox management. is this the option to enable what is described  
here for dovecot: http://wiki2.dovecot.org/Authentication/MasterUsers  
? or is it something different, because i can't find something in the  
dovecot wiki what is meant by 'userhierarchy' setting in the backends  
file.
