Exchange 2007 Setup in SBS 2008

Hello - I just setup a new Windows SBS 2008, Standard server and am able to send email internally using Exchange 2007, however I am not having any luck sending or receiving email.  

What obvious configuration in EMC 2007 am I forgetting to setup?

Many thanks.

If you don't have an Edge server then you do not have a connector with anonymous authentication enabled. You need to adjust the properties of the Default Receive Connector to allow anonymous access. You do not need to create a new Receive Connector.

Ref : 

Have you configured a Send Connector?
Under Organisation Configuration > Hub Transport > Send Connector
you need to setup a connector with an address space of * to use either DNS or smarthost.

If you use DNS then you need to configure a rDNS(PTR) record for say an A record in your external DNS for that points to the external IP of your network (Find out what your external IP is by going to )

Then on the FQDN section of your send connector enter

ypu will also need to setup an SPF record see:

Hope this helps.

Excellent have completed all the steps minus the SPF record.  Is this a "nice to have" or required would you say and if so, why?
SPF is nice to have until your users get random denials of sending email. A great site to help make one is

I've over done one for as an example. Also good to check your dns running the dns report from

Another good thing to do is to make sure you have reverse dns setup with your ISP correctly.
