Exchange 2007 (part of SBS 2008) Problem after installing Roll Up 15 for Exchange SP3

So I decide to do Windows updates on Small Business Server 2008, including a roll up for Exchange.
Previous Roll ups have been installed no problem.

I installed rollup 15, as recommended by Windows update.

After the updates are done, I email a couple accounts and I get the exact same error:

OK rejected your message to the following email addresses:

2ndfloor@myemail.ca (2ndfloor@myemail.ca)

OK gave this error:
No description

A problem occurred while delivering this message to this email address. Try sending this message again. If the problem continues, please contact your helpdesk.

Diagnostic information for administrators:

Generating server: Lisa.mycompany.ca

OK #550 No description ##

Original message headers:

So I can send out with no problems.

DNS for the mail record is fine and our External IP has not changed.

I tried sending to other accounts and from my Yahoo address and there is no change.
Spam filter is Exchange an is on and SCL is set to 5, but I don't think it's making it that far.  Since the email is bouncing back and not be forwarded to the Spam catch all account on the Small Business Server.

So I went into the Server and uninstalled the roll up , but it still does the exact same thing (left all other updates in for now).

Any suggestions would be helpful, as this is a production server.

Thank you

Hi Just Reviewed the system logs and here are two interesting entries:

Event ID: 1032
Receive connector requires Transport Layer Security (TLS) before the MailFrom command can be run, but the server can't achieve it. Check the authentication settings of this connector.

On another EE issue, someone recommends installing a fix made for Vista 64 bit, 372273_intl_x64_zip.exe, from Microsoft's website, anyone use it?

I would revisit the connectors to ensure nothing changed after deploying the ru

Run the Fix My Network wizard in the SBS Console, this should detect and repair the error with the Exchange connectors.

Hi everyone,
I already ran the Fix my Network wizard and it didn't find any problems with the network other than a warning about DNS using forwarding and not root hints.

I disabled the 4 receive connectors and recreated it and it seemed to have worked.

Thanks everyone!
