Public Function Subscribe() As ImapResponse

Dim instance As Mailbox
Dim value As ImapResponse

public ImapResponse Subscribe()

public: ImapResponse* Subscribe();

public:
ImapResponse^ Subscribe();

Return Value

An ImapResponse object encapsulating the response from the server.

Exception	Description
ProtocolException	Bad IMAP protocol response received from server.
System.Net.Sockets.SocketException	A communications failure has occurred.

This method sends the SUBSCRIBE command to the server, which adds the mailbox to the server's set of the user's subscribed mailboxes.

To get a list of subscribed mailboxes use

Imap.List("", "%", true);

This example demonstrates how to create, rename and delete a mailbox. It also shows how to subscribe and unsubscribe a mailbox.

C#

private void doMailboxFunctions(object sender)
{
    //Configure server and account info
    imap1.Session.RemoteEndPoint = new Dart.Mail.IPEndPoint(myServer, Imap.GetDefaultPort(imap1.Session));
    imap1.Session.Username = myUsername;
    imap1.Session.Password = myPassword;

    //Connect and log into the account
    imap1.Connect();
    imap1.Authenticate();

    //Create a mailbox
    Mailbox newBox = imap1.Mailboxes.Add("My_New_Box");

    //Subscribe the mailbox and check the subscribed list
    newBox.Subscribe();
    //Get all subscribed mailboxes
    List<Mailbox> list = imap1.List("", "%", true).ToList<Mailbox>();
    if (!list.Contains(newBox)) throw new Exception("Server did not subscribe the mailbox.");

    //Unsubscribe the mailbox and check the subscribed list
    newBox.Unsubscribe();
    list = imap1.List("", "%", true).ToList<Mailbox>();
    if (list.Contains(newBox)) throw new Exception("Server did not unsubscribe the mailbox.");

    //Rename the mailbox and then delete it
    newBox.Name = newBox.Name + "_Renamed";
    imap1.Mailboxes.Remove(newBox);

    //Gracefully logout of the session
    imap1.Close();
}
