Question about ITERINDEX in 2.2.32

[María Arrea]

Hello

    I have a question about the new setting ITERINDEX. This is my 
filesystem layout

    /indices_dovecot : 8 x Fast SSD drives
    /buzones : 32x SAS 10k rpm disks
    /buzones/alternativo : 24 x SAS 7.2k rpm slow disks

    This is my mail_location:

mail_location = 
mdbox:/buzones/domain/%2.26Hn/%2.200Hn/%n:INDEX=/indices_dovecot/indices/%2.26Hn/%2.200Hn/%n:ALT=/buzones/alternativo/domain/%2.26Hn/%2.200Hn/%n 



    What should I write in mail_location with the new ITERINDEX setting?

    Regards

    María
