the source to the ssl version of this is here: http://atmospherian.wordpress.com/downloads/

Answer 3

As the author of the above project i can say that yes it does support SSL. I am currently working on a new version of the library that will be completely asynchronous to increase the speed with which it can interact with IMAP servers. That code, while not complete, can be downloaded, along with the original synchronous library (which also supports SSL), from the code plex site linked to above.

thanks for the reference lakshmanaraj :)

Lumisoft.net has both IMAP client and server code that you can use.

I've used it to download email from Gmail. The object model isn't the best, but it is workable, and seems to be rather flexible and stable.

Here is the partial result of my spike to use it. It fetches the first 10 headers with envelopes, and then fetches the full message:

using (var client = new IMAP_Client())
{
    client.Connect(_hostname, _port, _useSsl);
    client.Authenticate(_username, _password);
    client.SelectFolder("INBOX");
     var sequence = new IMAP_SequenceSet();
    sequence.Parse("0:10");
    var fetchItems = client.FetchMessages(sequence, IMAP_FetchItem_Flags.Envelope | IMAP_FetchItlags.UID,
                                        false, true);
    foreach (var fetchItem in fetchItems)
    {
        Console.Out.WriteLine("message.UID = {0}", fetchItem.UID);
        Console.Out.WriteLine("message.Envelope.From = {0}", fetchItem.Envelope.From);
        Console.Out.WriteLine("message.Envelope.To = {0}", fetchItem.Envelope.To);
        Console.Out.WriteLine("message.Envelope.Subject = {0}", fetchItem.Envelope.Subject);
        Console.Out.WriteLine("message.Envelope.MessageID = {0}", fetchItem.Envelope.MessageID);
    }
    Console.Out.WriteLine("Fetching bodies");
    foreach (var fetchItem in client.FetchMessages(sequence, IMAP_FetchItem_Flags.All, false, true)
    {             
        var email = LumiSoft.Net.Mail.Mail_Message.ParseFromByte(fetchItem.MessageData);             
        Console.Out.WriteLine("email.BodyText = {0}", email.BodyText);

    }
}

I Used Lumisoft coding. From,to fields are rereived in mailbox format. Can anybody tell me how to convert mailbox to string. It's just displaying as "LumiSoft.Net.Mail.Mail_t_Mailbox[]". How to convert this to string??

Pls help

Answer 6

@Shalini - that's because From and To are arrays of FetchItems that have more information inside (e.g. Display Name, domain, etc.), so to get just all the From email addresses, do something like:

foreach (var fAddress In fetchItem.Envelope.From)
{
      Console.Out.WriteLine("message.Envelope.From = {0}", fAddress.Address);
}

There is no .NET framework support for IMAP. You'll need to use some 3rd party component.

Try Mail.dll email component, it's very affordable and easy to use, it also supports SSL:

using(Imap imap = new Imap())
{
    imap.ConnectSSL("imap.company.com");
    imap.Login("user", "password");

    imap.SelectInbox();
    List<long> uids = imap.SearchFlag(Flag.Unseen);
    foreach (long uid in uids)
    {
        string eml = imap.GetMessageByUID(uid);
        IMail message = new MailBuilder()
            .CreateFromEml(eml);

        Console.WriteLine(message.Subject);
        Console.WriteLine(message.TextDataString);
    }
    imap.Close(true);
}

Please note that this is a commercial product I've created.
