title: Send mail with SMTP adapter with retry, retryinterval and delivery notification
body: <p>I have an orchestration that receives an XML with some email properties(like: to, from, cc, subject, etc..).</p>
  
  <p>Then I want to send the emailmessage with a dynamic port (and I assigned some of the values according the input xml). After the email has been sent, I want to do some further processing but that processing may only execute when the mail has been delivered succesfully on the SMTP server.</p>
  
  <p>In the functional design they want to have a retry per hour and maximum of one day, after that periode a message must be in the EventLog when it cannot be delivered successfully. </p>
  
  <p>Therefore I set the dynamic port with the context properties BTS.RetryCount to 23 and BTS.RetryInterval to 60.</p>
  
  <p>I have set the dynamic SMTP port delivery notification to "Transmitted" and I have a catch exception block to catch the DeliveryFailureException.</p>
  
  <p>Is this enough ?</p>
  
  <p>It is a litte bit confusing for me reading several blogs if I should mark the scope Synchronized...</p>
