sending mail marked spam into junk

[maumar]

i have a mailgw in front of a lot of servers, zimbra and not;
some emails are marked spam with usual
*** SPAM ***
by amavis on mailgw and with such an object reach zimbra

then, zimbra delivers these mails on inbox.

question is:
how can i accomodate zimbra configuration to get these mails delivered into *junk* folder instead of inbox?

the preferred way to handle this is to not modify the subject, but to add an additional header to the e-mails at mailgw, something like

IsSpam: yes

then modify the zimbra global config variables

zimbraSpamHeader: IsSpam
zimbraSpamHeaderValue: Yes

then it will automatically put it in the junk folder

that's interesting...
but i have searched for zimbraSpamHeader
and i have found this
Multi zimbraSpamHeader Values

This is true, sadly ;(
