Problem with mailkit on raspbian mono

[RQuinve]

Steps to Reproduce

Hello, I have a little program (c#) that works with Imap client (MailKit). This app works very well on my windows 10 x64. I want to use it on my raspberry pi 3+, but it hangs when it gets messages.

My app manage messages in my email box. Currently it gets configuration from web server, so there is no interaction with system. It get messages from a custom folder "My Anti-Spam/A_Bannir". If message is in black list, it deletes it.

Here is my test class:

`

internal class Toto { internal void Clean() { string serveurAdresse = "my_server"; int serveurPort = 993; bool useSsl = true; string utilisateur = "my_account"; string motDePasse = "my_password";

  try
  {
    using (ImapClient client = new ImapClient(new ProtocolLogger("mailkit.log")))
    //using (ImapClient client = new ImapClient())
    {
      // For demo-purposes, accept all SSL certificates
      client.ServerCertificateValidationCallback = (s, c, h, e1) => true;
      client.Timeout = 20000;
      //client.Connect(serveurAdresse, serveurPort, useSsl);

      if (useSsl)
      {
        client.Connect(serveurAdresse, serveurPort, SecureSocketOptions.SslOnConnect);
      }
      else
      {
        client.Connect(serveurAdresse, serveurPort, SecureSocketOptions.None);
      }

      if (!client.IsConnected)
      {
        return;
      }

      // Note: since we don't have an OAuth2 token, disable
      // the XOAUTH2 authentication mechanism.
      client.AuthenticationMechanisms.Remove("XOAUTH2");
      client.Authenticate(utilisateur, motDePasse);

if DEBUG

      if (client.Capabilities.HasFlag(ImapCapabilities.Id))
      {
        var clientImplementation = new ImapImplementation { Name = "MailKit", Version = "1.0" };
        var serverImplementation = client.Identify(clientImplementation);

        Console.WriteLine("Server implementation details:");

        foreach (var property in serverImplementation.Properties)
        {
          Console.WriteLine("  {0} = {1}", property.Key, property.Value);
        }
      }

endif

      // on définit la destination Inbox
      IMailFolder inbox = client.GetFolder("INBOX");

      // on définit la destination poubelle
      IMailFolder poubelle = client.GetFolder("Trash");

      client.Disconnect(true);
    }
  }
  catch (Exception ex)

private void ABannirProcess(ImapClient client, IMailFolder inbox, IMailFolder poubelle)

  // on définit le dossier à récupérer
  IMailFolder aBannir = client.GetFolder("My Anti-Spam/A_Bannir");
  aBannir.Open(FolderAccess.ReadWrite);

  Console.WriteLine("01");

  try

  }

  aBannir.Close();

  // update remote server
  LesListes.SetServerLists();

}

`

Current Behavior

The app hangs at line

`

---

// get messages var items = aBannir.Fetch(uids, MessageSummaryItems.UniqueId | MessageSummaryItems.Envelope);

---

`

instead having messages

Can you help me please?

That's a very, very old version of Mono. Can you try updating?

[RQuinve]

Hi, Thank you for your response. I am surprised because I just typed : sudo apt-get install mono-complete So where is my problem please ?

Regards.

Follow the download instructions on mono-project.com to download our latest builds, not the version in your distribution repository (which may be several years old)
