title: Send email from bot framework FormFlow
body: <p>I have an example bot created using FormFlow:</p>
  
  <pre><code>public static IForm&lt;SandwichOrder&gt; BuildForm()
          {
              OnCompletionAsyncDelegate&lt;SandwichOrder&gt; processOrder = async (context, state) =&gt;
              {
                  await context.PostAsync("We are currently processing your sandwich. We will message you the status.");
              };
  
              return new FormBuilder&lt;SandwichOrder&gt;()
                          .Message("Welcome to the sandwich order bot!")
                          .Field(nameof(Sandwich))
                          .Field(nameof(Length))
                          .Field(nameof(Bread))
                          .Field(nameof(Cheese))
                          .AddRemainingFields()
                          .Message("Thanks for ordering a sandwich!")
                          .OnCompletion(processOrder)
                          .Build();
      }
  </code></pre>
  
  <p>On completion of form, the control comes at:</p>
  
  <pre><code>OnCompletionAsyncDelegate&lt;SandwichOrder&gt; processOrder = async (context, state) =&gt;
                  {
                      await context.PostAsync("We are currently processing your sandwich. We will message you the status.");
                  };
  </code></pre>
  
  <p>I want to send an email to myself with all the form fields. How can I connect with SMTP and write an email function to send an email with all selected options and inputs from user?</p>
