It will never catch it. Here's one I got today:

See how the Message-ID is attached to the previous line?  How the From  
is also? And the Subject, Date, etc?

The filters rely on the information in these headers, and since these  
headers are 'not there' the information can never be parsed, and  
nothing about the message will be learned.

I only see these going to .mac/MobileMe, so I suspect that something  
in MobileMe's mailservers is seeing these as spam and munging them  
badly (less likely), or that the messages are being submitted with  
Windows style EOLs assuming that the mailserver will parse them (more  
likely).

This specific message originated from 124.80.99.17 (in the headers I  
didn't paste) and that address is listed in blacklists.

$ dig 17.99.80.124.zen.spamhaus.org +short
127.0.0.11

I don't see messages like this on my own mailserver, but then I  
wouldn't as I reject address listen in zen.

But don't bother trying to train the Junk Filters for those messages,  
there's nothing in the headers for it to train on, just delete them.
