Summary: spam gets through, totally unmarked

Initial Comment:
I set the spambayes as a local POP3 server, so all my
mail goes through it. I was working fine, and was
catching 95% of the spam after i trained it. I set it
up so it was marking the header as spam, ham or unsure,
so i can sort my mail withing my mail client (outlook
express). I send all messages marked "spam" to the
deleted folder. 

But then like three days ago i started getting some of
the spam without ANY marks in the header, and now i get
like 10-15% of the spam right into my inbox. 

Does anybody know how to fix that?

thanks!

I have observed a new technique used by spammers: they
inundate a (personal/virtual) server with dozens of idle
SMTP connections - usually from different source IPs using
zombies - where each  forks a new smtpd process until no
more connections can be made due to the limit on number of
processes by one user, then they send their spam through one
of the connections. Now, if procmail is used for filtering,
 a fork to call spambayes will fail, and therefore the
rescued original text will be  delivered to the mailbox
based on the default rule.  You may be better off setting a
rule to put unmarked messages to the unsure box.

Take a look at the headers for the mail.  Is there a
"X-Spambayes-Exception" header?  If so, what does it say?

What do the log files say?  The troubleshooting guide
explains where to find the log files.
