Yes, it is. You may use exiscan the same way you're using your system
filter now. It may simply flag and then accept messages, or reject,
teergrub or do nothing on them - as you like.

What you're missing is the 'unseen' option here. This router/transport
combination performs what you want, I think - watch out - it's Maildir
format:

ROUTER:
backup_incoming:
driver = redirect
domains = +local_domains
senders = !*@+local_domains
condition = "${if {eq {$received_protocol}{spam-scanned}} {0}{1}}"
directory_transport = backup_2_maildir
data = BACKUPDIR/Incoming/
unseen

TRANSPORT:
backup_2_maildir:
driver = appendfile
create_directory
directory_mode = 0770
mode = 0660
maildir_format

Place it before your 'local_user' router. The position of the transport
doesn't matter as long as you place it in the transport section at all
;)

hth,
