Create namespace

namespace {
   hidden = no
   ignore_on_failure = no
   inbox = no
   list = yes
   location = 
maildir:/var/mail/%d%n/test1:LAYOUT=fs:DIRNAME=maildirfolder:UTF-8
   mailbox next {
     auto = subscribe
     special_use =
   }
   prefix = Тест1/
   separator = /
   subscriptions = yes
   type = private
}
namespace {
   hidden = no
   ignore_on_failure = no
   inbox = no
   list = yes
   location = 
maildir:/var/mail/%d%n/test2:LAYOUT=fs:DIRNAME=maildirfolder:UTF-8
   mailbox next {
     auto = subscribe
     special_use =
   }
   prefix = &BCIENQRBBEI-2/
   separator = /
   subscriptions = yes
   type = private
