[Spambayes] why doesn't the pop3 proxy filter all messages?

Are you positive that Eudora is connecting via localhost and not directly to
the POP3 server?  It should not be possible for a message to get through the
SpamBayes POP3 proxy without getting either a classification header or an
exception header.

What happens if you telnet to the proxy?  For example (do this from a
Command/DOS prompt):

telnet localhost 110
[wait for the connection]
USER [username]
PASS [password]
RETR 1
QUIT

That should print out to the console the first message waiting to be
downloaded (it will not be deleted, so it'll still be delivered in a regular
mail check).  Does that include any SpamBayes headers?

If you run sb_server from a command line, you can add "-o
globals:verbose:True" to the end.  Otherwise, you need to open up the
configuration file (probably called "bayescustomize.ini", and probably in
"C:\Documents and Settings\{username}\Application Data\Spambayes\Proxy" -
the FAQ explains alternative locations) and add these lines:

[globals]
verbose:True

However, I suspect that you won't get anything in the logs.  I could be
wrong, though.
