Changing MX to forward to Barracuda Email Security Service Explanation

Hi All,

My company recently purchased Barracuda Spam and Email Security Service (Cloud service for cloud mail users)

My company asked me exactly how this works, All we were told was to update our MX address which we did.

I explained when we send mail... Our email gets sent to our email server like normal but with the updated mx record then our outgoing emails will be forwarded through the Barracuda network then sent to the recipient ... (or is the mail sent to the barracuda networks then sent back to our mail server then resent out? )


For incoming mail the mail is received at our server but then forwarded to Barracuda and then sent from Barracuda to our  incoming mail server

That is how it works correct? I just want to make sure I explain it correctly.

Thanks
