issue with new ISP using our email server

Using SBS2011 with Exchange 2010
We changed ISP so our IP address changed
I did the changes to our firewall and our MX and A records
I also had our new provider do a rDNS for our email server

I remember back in SBS 2003 if I had any changes on our ISP or firewall
I would need to run a wizard on SBS2003 to fix email which would look at my firewall 192.168.1.1 then prompt me for the new ISP DNS IP Address. After this email would work just fine.

Do I need to do something like this in SBS 2011?

here is an example of our emails bouncing back:

VA3EHSMHS009.bigfish.com rejected your message to the following e-mail addresses:
(username@dot.ca.gov) <mailto:username@dot.ca.gov>


VA3EHSMHS009.bigfish.com gave this error:
Service unavailable; Client host [xx.xx.xxx.xxx] blocked using Blocklist 1, mail from IP banned; To request removal from this list please forward this message to delist@messaging.microsoft.com and include your ip address xxx.xxx.xxx.xxx

this happens to some of our clients not all
