Check your DNS for the proper A and PTR records for your exchange server. Also check permissions on send and receive connectors and post the result.

Check that, everything seems normal, any other ideas? Some users can send externally and some cannot.

Can you provide more information about how you send/receive email Are you using a POP Connector? Your public MX records do not appear to be set up for you to send/receive email directly from your server. It looks like your email goes through your web host..

There is a good chance that this is caused by incorrect reverse DNS (public reverse DNS, not the PTR records on your own server) or an incorrect SPF record.  If you telnet from your server to port 25 of a remote mail server and try to send a message that way, the response from the server may give you more information about what isn't working.

Did you install Exchange 2010 on the SBS 2008 server or a second server?
Did you remove the Exchagne 2007 server

Hmmmm.  Yeah, I just realized you said Exchange 2010 on SBS.  Are you running a pre-release version of SBS 2011?

From the question - you appear to be sending out as:

From: Jeff Moscone <Jeff@lfe.local>

As .local domains are simply used for internal use and are not internet routable and cannot be resolved in DNS - it would suggest your Recipient Policy is not working and you need to change it to reflect your proper domain name.

Anyone trying to check your domain name is valid will be unable to and hence you will get Sender Verification failures.

Also - if your server SEND connector is configured as servername.lfe.local - it will also cause you failure problems.
