Hi, Since a few hours back i'm recieving mails containing the new Bagle.B virus. I'm using a RH9 box with Postfix and SA and relaying mail for a Exchange 5.5 mailserver.
The virusmail is spoofing our adressess. Virusmails are recieved from a infected computer somewhere in the world. But the sender and recipient are users in our directory. How can i reject these messages before they're relayed to our Exchangeserver? Thank you
