I am creating 2 desktop applications in c # with netframework 4.7. In one application I am sending mail by smtp to the outlook server of 365, and in another I am reading the mail through imap.
I'm using @jstedfast 's MailKit library and I'm following this answer as I'm interested in my application handling the delivery status of the mails. The problem I have is that in the delivery status emails I am not receiving the Original-Envelope-Id header.
So what could I be doing wrong? Is it a missing configuration on the outlook server? Is it a missing configuration in the library?
Currently my classes are like this:
The classes and methods that send the mail:
public class EnvioDeCorreo {
private const string Usuario = "miusuario@outlook.com";
private const string Password = "mipass";
private const string Host = "smtp.office365.com";
public async Task Enviar() {
var message = new MimeMessage();
message.From.Add(new MailboxAddress("PrFq", Usuario));
message.To.Add(new MailboxAddress("usu1", "usu1@gmail.com"));
message.To.Add(new MailboxAddress("notvalid", "notvalid.notvalid@notexist.com"));
// Adding others mailbox's
message.Subject = "Hola de envio desde c#";
message.Body = new TextPart("plain") {
Text = "Hola desde c#"
};
using (var client = new DSNSmtpClient(new ProtocolLogger("DSNSmtpClient.log"))) {
client.MessageSent += this.OnMessageSent;
await client.ConnectAsync(Host, 587, SecureSocketOptions.StartTls);
await client.AuthenticateAsync(Usuario, Password);
if (client.Capabilities.HasFlag(SmtpCapabilities.Dsn))
Debug.WriteLine("Soporta DSN");
else return;
await client.SendAsync(message);
await client.DisconnectAsync(true);
}
}
private void OnMessageSent(object sender, MessageSentEventArgs e)
=> Debug.WriteLine($"En MessageSent {e.Response}");
}
public class DSNSmtpClient : SmtpClient {
public DSNSmtpClient(ProtocolLogger protocolLogger) : base(protocolLogger) { }
protected override string GetEnvelopeId(MimeMessage message) => message.MessageId;
protected override DeliveryStatusNotification? GetDeliveryStatusNotifications(MimeMessage message, MailboxAddress mailbox)
=> DeliveryStatusNotification.Failure | DeliveryStatusNotification.Success;
The class that consults the emails:
public class ManejoDeEstadoDeCorreo {
private const string Usuario = "miusuario@outlook.com";
private const string Password = "mipass";
private const string Host = "outlook.office365.com";
public void Manejar() {
using (var client = new ImapClient(new ProtocolLogger("ImapClient.log"))) {
client.Connect(Host, 993, true);
client.Authenticate(Usuario, Password);
var inboxFolder = client.Inbox;
inboxFolder.Open(FolderAccess.ReadOnly);
var query = SearchQuery.SubjectContains("Hola de envio desde c#");
var uids = inboxFolder.Search(query);
foreach (var uid in uids) {
var message = inboxFolder.GetMessage(uid);
this.ValidarEstado(message);
}
client.Disconnect(true);
}
}
private void ValidarEstado(MimeMessage message) {
var report = message.Body as MultipartReport;
if (report != null && report.ReportType != null
&& report.ReportType.Equals ("delivery-status", StringComparison.OrdinalIgnoreCase)) {
foreach (var mds in report.OfType<MessageDeliveryStatus>()) {
var statusGroup = mds.StatusGroups[0];
var envId = statusGroup["Original-Envelope-Id"];
if (envId is null) {
// It is here where the header is null.
Debug.WriteLine("Not working");
} else {
}
}
}
}
}
