I have an interesting issue getting message body text using the BounceResult  class.   The issue is I can read body text from some bounce notification emails  - but not others.   I am using an Guid included in the sent emails as a reference id to write back statuses to a database and need to get the original message text to extract the Guid.  

                                                   

All email is sent in the same manner with the following delivery notification properties set as shown:



smtpClient.DeliveryStatusNotificationReturnMessageMethod 

      =   DeliveryStatusNotificationReturnMessageMethod.FullMessage; 

smtpClient.DeliveryStatusNotificationType 

      = DeliveryStatusNotificationType.All;



Here is the code I am using to read the original message texts:



  foreach (BounceResult r in result)

                {

                    if (r.Identified)

                    {

                        string messageId = "none found";

                        foreach (Attachment at in r.MailMessage.Attachments)

                        {

                            if ( at.Message != null )

                            {

                                string bodyText = at.Message.BodyText;

                                // extract message id

                                int regIndex = bodyText.IndexOf("ref:",StringComparison.CurrentCulture);

                                messageId = bodyText.Substring(regIndex + 4, Guid.Empty.ToString().Length);

                             }

                        }

                        // Update message status....

                    }



For the email bounce notification messages that I can read the bodyText there is Dsn.Action and  Dsn.DiagnosticCode information.  For the emails that do not have bodyText there is no DDsn.Action orDsn.DiagnosticCode information.



I am using UltimateEmail trial edition at the moment and have the full-source corporate licensed version ordered.



I am using gmail as a development imap server.



More Info:



The mail bounce messages that I can read the bodyText from are those that are sent to existing domains in which the recipient does not exist.  The ones I cannot read the bodyText from are sent to nonexistent domains.  





Thanks

chris
