Mailflow issue when getting exchange 2007 and exchange 2010 to coexist

I have migrated a test mailbox over to the new exchange 2010 server-

 I am able to receive en email from an internal domain user email account but cannot send to an internal domain user email account

 I am able to send to an external email address and can receive email from an external email address
