First this is an INTERESTING effort you are making and I
would like to be kept informed of your progress.

But please allow a clarification: Those suggesting ClamAV
are referring to the apparently fact that ClamAV goes beyond
pure "virus scanning" and is also checking for some of these
phishing scams.

It may or may not do all that you wish -- or you may do well
to inform the ClamAV signature developers of your results...

Cool.

The most interesting result would be mechanisms for
distinguishing valid emails from invalid ones and
malicious emails.

Here are some more (decent) leads:
