Adding a custom signature

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

using System.Windows.Forms;
using ComponentPro.Net.Mail;

...

const int myCategoryCode = 1000; // The category code. 
const int myTypeCode = 1000; // The type code. 
try
{
    // 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",
                            System.IO.Path.GetFileName(r.FilePath),
                            r.MailMessage.Subject,
                            r.Addresses[0],
                            r.BounceCategory.Name,
                            r.BounceType.Name,
                            r.FileDeleted,
                            r.Dsn.Action,
                            r.Dsn.DiagnosticCode);
        }
    }

    // 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. 
    inspector.RemoveSignature(signatureIndex);

    // Do something here. 
    // ... 
 
    Console.WriteLine("{0} bounced message found", result.BounceCount);
}

{
    MessageBox.Show(string.Format("An error occurred: {0}", exc.Message));
