In  3.4 altnamespace true became the default :

    altnamespace: 1
       Use the alternate IMAP namespace, where personal folders reside  
at the same level in the hierarchy as INBOX.

It has. It's the IMP nav_poll options :
nav_poll: a:2:{s:5:"INBOX";i:1;s:10:"INBOX.test";b:1;}

nav_poll should become ;
nav_poll: a:2:{s:5:"INBOX";i:1;s:10:"test";b:1;}

Sincerly,
