missing "X-Bogosity" line

[David Relson]

Greetings,

As happens several times a day, a spam message snuck past bogofilter.  As I 
moved it to my spam-fixups (for reprocessing via "bogofilter -S"), I 
noticed that the message was missing its "X-Bogosity:" header.

Looking at my syslog I notice that the normal bogofilter log message is 
also missing.

Here're the log entries for this message:

Oct 25 18:00:08 nic postfix/smtpd[30788]: connect from unknown[157.238.181.133]

("|/usr/bin/procmail -Y -a $DOMAIN")

Here're the normal log entries for the next email that came in.  Notice it 
_does_ have the bogofilter message:

Oct 25 18:02:26 nic postfix/smtpd[30910]: connect from

One coincidence I noticed is that the message came in at 18:00:09 and every 
hour I run a script to do spam-fixups, i.e. feed mis-classified messages 
back into the wordlists.  One of the script's actions is to dump the 
wordlists (using bogofilter).  I often notice the script running because I 
hear the server's disk running for a while (multiple seconds).

Could there be a locking issue?

Has anyone else noticed messages missing expected "X-Bogosity" lines?

Cheers!
