Environment:
Sharepoint 2013 SP1 (Standalone) on WS2008R2
Workflow Manager 1.0
Active Directory on WS2008R2 and Exchange Server 2010 on WS2008R2
Steps:
Install Sharepoint 2013 (Non-SP1) and configure to send e-mail
Set Workflow Manager with HTTP connection
Open Sharepoint Designer, choose Sharepoint 2013 Workflow, add "send e-mail" action
Run Workflow and send e-mail successfully
Upgraded Sharepoint 2013 SP1
Run Workflow and send e-mail fails
We tried new install on SP2013SP1 but fails as same(SP2010 Workflow can send e-mail)
I have installed Fiddler and monitored HTTP message.

Any advice would be helpful.
