Scanning outbound emails

ITKE — Tue, 17 Aug 2010 20:27:18 +0000

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.

Cisco ASA 5505 Limit IP that can send mail to the Internal network

Edctech — Fri, 08 May 2009 03:10:36 +0000

We have a spam blocker that sits on the Internet and forwards clean mail to our Exchange server. The MX record points to this IP, but we are still getting a lot of spam that never passes through our spam blocker. I have confirmed that it is not an internal spambot.
Question: How do I configure the ASA to only allow the Spam blocker IP to send mail to our internal network?

Email Security – Verify Sender

Maryam82 — Sun, 01 Mar 2009 13:07:51 +0000

An email was sent to some of our users and the sender appears to be one of our company’s users and he didn’t send it because it shows on our gateway filter. Emails between our company’s users are handled by exchange itself.
After checking the filter gateway the message ID = ….@filter.gateway.com
And accepted from unknown IP 69.20.5.219
Reverse DNS lookup is enable on filter gateway …
How can we prevent this from happening again?
Not to accept emails with our users emails in from field unless it was originated from the user himself.
