[Dovecot] lazy_expunge plugin with virtual mailboxes

Hi,

When using both lazy_expunge and virtual mailboxes (with, for instance, a "All Messages" virtual mailbox) as soon as a user deletes/expunges a mail in one of its mailbox, Dovecot is saving two mails to the lazy_expunge namespace (the one in the user mailbox and the one in the virtual mailbox).

Is there some kind of trick to make Dovecot ignore any mail deleted from a virtual mailbox namespace ?

Thanks, Gilles.
