We have been compromised and one email account is internally sending out a lot of spam. We shut it down and another machine popped up infected and doing the same thing. How can we scan all out bound emails for spam just like incoming email? We use a barracuda 300 spam firewall.

    A word of advice: disable outbound TCP port 25 from all devices except your trusted network edge systems until you can get the issue addressed. This will keep your domain/IP off of blacklists.
