Email Submission Client issue with IIS bindings.

Resolution

If going to the CAS URL for SESC gives this: system.serviceModel/serviceHostingEnvironment/multipleSiteBindingsEnabled' to true

then the IIS config is not allowing multiple servers to use SSL/TLS. IIS needs to be configured to make this binding true. After configuring this in IIS, restarting the IIS and SESC services will allow submissions again.
