The mailing list for listmasters using Sympa

[address@concealed]

We have a mail gateway that is our primary spam filter. It runs MailScanner
with SpamAssassin. It marks all messages it considers spam by placing 
"{Spam?}"
in the subject line and adds the entry "X-nami-MailScanner-SpamCheck: spam" to
the header. This header entry is not added if the gateway thinks the message 
is
"ham". Mail must always pass through this gateway before the sympa server sees
it.

I want to create a send scenario that will allow members to post to a list and
non-members to be moderated, WITH THE EXCEPTION that any message the gateway
considers spam gets rejected outright. I based my new scenario off
send.privateoreditorkey. Here's what I've created so far:

FILENAME: send.privateoreditorkeynospam

CONTENTS:

title.gettext Private, moderated for non subscribers, rejects messages marked
{Spam?}

is_subscriber([listname],[sender]) smtp,smime,md5    -> do_it
is_editor([listname],[sender])     smtp,smime,md5    -> do_it
match([header->X-nami-MailScanner-SpamCheck],/yes/) smtp -> reject
true()                             smtp,smime,md5    -> editorkey


Is this correct? Apologies for the proofread question, I'm still a little hazy
on just how many options the scenari scheme gives me.
