outlook idiocy - IMAP folders with /

[Wojciech Puchar]

user attempts to create folders with / 
dovecot naturally cannot create it so it returns error but outlook of 
course "create" it and keep data in local store only. data is lost when 
you remove local store .pst file.

The question is - can dovecot be configured so it will automatically 
replace slash in name with something else?
