You should be able to do this with constructor injection, like this:

private readonly IEmailServices _emailServices;

public UserServices(IEmailServices emailServices)
{
    _emailServices = emailServices;
}

The service injection into your controllers should be handled automatically by the Ninject custom controller factory, which'll use the configured IoC container to resolve the IUserServices object when the controller is created, which will in turn be given an IEmailServices object by the container:

public class MyController : Controller
{
    private readonly IUserServices _userServices;

    public MyController(IUserServices userServices)
    {
        _userServices = userServices;
    }
}

When you're unit testing, you can manually inject a fake or mock email service into the user service.
