mdbox_deleted proper syntax

[Johan Huldtgren]

hello,

on the wiki, https://wiki2.dovecot.org/MailboxFormat/dbox, it says that one can
use either doveadm fetch or doveadm import, however I can find no correct syntax
with fetch that'll actually work. Is the idea to simply override the
mail_location with -o ? That seems to work for doveadm mailbox but not for
doveadm fetch or search

# doveadm -f table mailbox status -u johan all dovecot
mailbox messages recent uidnext uidvalidity unseen highestmodseq vsize     guid                             firstsaved

What I'm really trying to accomplish is see if a mail which a user deleted still exists in mdbox_deleted, so I
wanted to do a fetch / search to see and then try to copy / import that message back.

This is on OpenBSD 6.3-current with dovecot 2.2.36, doveconf -n below.

thanks,
