      The following example illustrates how to use AddBounceSignature to add a custom signature to BounceInspector.

      using System;
      using System.Windows.Forms;
      using ComponentPro.Net.Mail;
      const int myCategoryCode = 1000; // The category code. 
      const int myTypeCode = 1000; // The type code. 
          // Create a new instance of the BounceInspector class. 
          BounceInspector inspector = new BounceInspector();
          // Add bounce category "My Category" with code 1000 to the inspector. 
          inspector.AddBounceCategory(myCategoryCode, "My Category");
          // Add bounce type "My Type" with code 1000 to the inspector. 
          inspector.AddBounceType(myTypeCode, "My Type");
          // Define a custom signature. 
          // Add signature with  
          // regex pattern: '(\S+@\S+\w).*\n?.*my custom signature' 
          // bounce category: 'My Category' 
          // bounce type: 'My Type' 
          // Delete messages: no 
          // analyze this signature first: yes 
          int signatureIndex = inspector.AddBounceSignature(@"(\S+@\S+\w).*\n?.*my custom signature", myCategoryCode, myTypeCode, false, true);
          // Define a custom signature. 
          // Add signature with  
          // regex pattern: '(\S+@\S+\w).*\n?.*nonexistent(?:\s|\n)domain' 
          // bounce category: DnsUnknown 
          // bounce type: Hard 
          // Delete messages: yes 
          // analyze this signature first: yes 
          inspector.AddBounceSignature(@"(\S+@\S+\w).*\n?.*nonexistent(?:\s|\n)domain", BounceCategory.DnsUnknown, BounceType.Hard, true, true);
          // Process all EML files in directory 'c:\\temp'. 
          BounceResultCollection result = inspector.ProcessMessages("c:\\temp");
          // Display processed emails. 
          foreach (BounceResult r in result)
              // If this message was identified as a bounced email message. 
              if (r.Identified)
                  // Print out the result 
                  Console.Write("FileName: {0}\nSubject: {1}\nAddress: {2}\nBounce Category: {3}\nBounce Type: {4}\nDeleted: {5}\nDSN Action: {6}\nDSN Diagnostic Code: {7}\n\n",
          // Modify the added signature to automatically delete all hard bounces. 
          inspector.ModifyBounceSignature(signatureIndex, @"(\S+@\S+\w).*\n?.*my custom signature", myCategoryCode, myTypeCode, true, BounceSignaturePart.Body | BounceSignaturePart.BodyHtml);
          // Process all EML files in directory 'c:\\temp2'. 
          result = inspector.ProcessMessages("c:\\temp2");
          // Process the result here. 
          // ... 
          // Remove the added signature. 
          // Do something here. 
          // ... 
          Console.WriteLine("{0} bounced message found", result.BounceCount);
      catch (Exception exc)
          MessageBox.Show(string.Format("An error occurred: {0}", exc.Message));
