[Dovecot] maildirmake -q quota equivalent to set quota

Hi,

I'm coming from courier-imap and i'm trying to migrate to dovecot.

I can't find how to create a maildir with a quota file(maildirsize)

I saw that if there was a maildirsize it would get its quota from there but can't find how to create that file.

I'm using pam auth and would like to set different quotas for each users.

With courier-imap there is a useful command : maildirmake -q 100000S Maildir/ to assign a quota to a maildir. But i don't know how to do with dovecot...

Cheers, Erc PEYREMORTE
