I don't "trust" a spam signature as much as a virus signature. My clamav
is direct on SMTP level and returns a 5xx error if you send me a virus.
If I load the unofficial signatures then they will also give my mail
messages a 5xx error.

I would like to see more like a spamassassin plugin kind of a sollution.
So ClamAV is still the AV as it is on the moment and gives away enough
reason to issue a 5xx error on every email if it contains a virus.

Spamassassin is called and asks ClamSA (a clam spamassassin plugin)
loaded with the unofficial signatures if a given message could be a
(phishing) spam message. And receive 3 or 4 out of the 5 points.

This way we are safe for FP from the unofficial signatures and we get
less spam in our inbox.
