Hi all, I already have spamassasin filter but yesturday one of the phishing mail send from "Barclays " nearly 1500 and make our mail queue jam around 500 and I lost all of those email. I defined as spam and it also coming into the spam quarantine. But spam quarantine size become bigger and bigger. Every few seconds its coming into quarantine. So I want to stop those email before it coming into our server. I know that some expert can do it better, but I don't know how to do it. Even they post the way to do in forum also I am not understand. Is anyone can help me?

Best Regards,
