Bypass external spam filter for exchange

We currently have our exchange email from the outside going through our spam filter but the spam filter has expired so we need to bypass it so our eternal email will come in again.
How can I do this as fast as possible? We are running exchange 2010

The mail should still continue to come into the organization, the spam filter just wont filter the mail for spam or malware, but it shouldn't block the mail from being delivered. Is this a spam filter that you own, or a service being provided by a hosted company. If you own it, it should be good to continue to allow mail to come in, but if hosted by a 3rd party and they are blocking the mail, then you will need to change your external MX record to point to your internet facing Exchange server or Firewall so that the mail will bypass the spam filter of the hosted company.

The email is bouncing back to the external users because their subscription ran out on the spam filter. So I need to get the email coming in again as fast as posible

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

Do you have a firewall at the perimeter of your network. If so, you need to point your external MX record to the firewall external IP address and that should be it. The firewall is most likely already setup to forward the mail to your Exchange server, but if not, you need to set the firewall to forward all mail on port 25 to your exchange internal IP.

tim,
Question we made the change for the mx record and now the external email users are not getting bounce backs any more but now it doesn't seem like our users are getting the external email. Is there something I have to do or does it take sometime for the external to come in since making the change?
I set the ttl to 3600
