dovecot - Apr 2013 - autocreate mailbox but no sub folders

Hello,

We have been using lda_mailbox_autocreate to avoid to intialize empty 
mailboxes upon account creations. This does the job allright except that 
dovecot-lda is also allowed to autocreate sub folders which is a problem 
when using addresses extensions (adress+folder at domain.tld). It's easy 
for a malicious user to flood a mailbox with tons of subfolders.

Is there a way to tell dovecot-lda it can only create the initial 
mailbox and maybe some special folders but nothing else?

Thanks,

Arnaud

INBOX is autocreated regardless of lda_mailbox_autocreate setting. So just set
it to "no".
