[Mimedefang] No more X-Spam-Score?

[Lisa Casey]

Hi,

I'm using Mimedefang/Spamassassin for spam.  I'm also using procmail to 
filter on mimedefang's X-Spam-Score header. This has been working fine until 
recently (I'm not certain exactly when). Mimedefang is no longer putting an 
X-Spam-Score into the headers. Instead I'm getting this:

X-Spam-Score:  ()

Mimedefang is scanning and scoring the email. The same email that had the 
X-Spam-Score I pasted above also contained the following Spam Report:

Content analysis details:   (20.6 points, 5.0 required)

 pts rule name              description
---- ---------------------- -----------------------------------------------=

 4.4 HELO_DYNAMIC_IPADDR2   Relay HELO'd using suspicious hostname (IP addr
                            2)
 4.2 HELO_DYNAMIC_SPLIT_IP  Relay HELO'd using suspicious hostname (Split
                            IP)
 0.5 TVD_RCVD_IP            TVD_RCVD_IP

 3.4 FUZZY_XPILL            BODY: Attempt to obfuscate words in spam
 0.0 HTML_MESSAGE           BODY: HTML included in message
 0.1 RDNS_DYNAMIC           Delivered to trusted network by host with
                            dynamic-looking rDNS
 3.0 MIME_CHARSET_FARAWAY   MIME character set indicates foreign language


I used to get stuff like the following for X-Spam-Score:

X-Spam-Score: 5.598 (*****) FIN_FREE,RDNS_DYNAMIC,SUBJ_YOUR_DEBT

I haven't changed any config files for Mimedefang or spamassassin. Where 
should I look to try to figure out why I'm not getting a X-Spam-Score now?

Thanks,
