[exim] Help with router

Hi all,

sorry to bother I'm new to exim and having difficulties setting up my server.

I configured Exim with SpamAssassin to rewrite the subject as follows 
in case of spam:
X-Spam-Status: Yes (5.5/1.0) SpamAssassin 3.2.0 (2007-05-01)
    (+++++)
    ---- Start of SpamAssassin Report
    *  0.5 TVD_RCVD_IP TVD_RCVD_IP
    *  0.0 UNPARSEABLE_RELAY Informational: message has 
unparseable relay lines
    *  0.0 HTML_MESSAGE BODY: HTML included in message
    *  2.3 MIME_HTML_ONLY BODY: Message only has text/html MIME parts
    *  1.0 MIME_HEADER_CTYPE_ONLY 'Content-Type' found without 
required MIME
    *      headers
    *  1.7 HTML_MIME_NO_HTML_TAG HTML-only message, but there is 
no HTML tag
    ---- End of SpamAssassin Report
Subject: [***SPAM***] spam subject

In case of non spam:

X-Spam-Status:    No (0.5/1.0) SpamAssassin 3.2.0 (2007-05-01) () ---- 
Start of SpamAssassin Report *  0.5 TVD_RCVD_IP TVD_RCVD_IP *  0.0 
UNPARSEABLE_RELAY Informational: message has unparseable relay lines 
---- End of SpamAssassin Report

I wish to filter the message based on the x-spam-status header and I
tried the following router trying to control if the x-spam-status
contains Yes

delspam:
driver = accept
condition = ${if match {$h_X-Spam-Status}{"Yes"} {Yes}{No}}
transport = rmspam


the condition never verifies.


Please help

Thank you
