Copy only the last instance (v2.2+)
If mail has multiple copies (via IMAP COPY), each copy is normally moved
to lazy expunge namespace when it's expunged. With v2.2+ you can set
plugin { lazy_expunge_only_last_instance = yes } to copy only the last
instance and immediately expunge the others. This may be useful if you
want to provide a flat list of all expunged mails without duplicates in
your webmail. With many clients this means that the last instance is
always in the Trash mailbox.
