Bulk mail download

Question

pls share code for bulk mail download with pop3 or imap

Answer 1

Generally none of the email protocols (IMAP, POP3) allow bulk email download, that would be significantly faster than downloading emails one by one.

Basic email download sample looks like this:

using(Imap imap = new Imap())
{
    imap.Connect("imap.server.com");  // or ConnectSSL for SSL
    imap.UseBestLogin("user", "password");
    imap.SelectInbox();
    List<long> uids = imap.Search(Flag.Unseen);
    foreach (long uid in uids)
    {
        IMail email = new MailBuilder()
            .CreateFromEml(imap.GetMessageByUID(uid));
        Console.WriteLine(email.Subject);
    }
    imap.Close();
}

Please note that entire emails is downloaded, this includes all attachments.

You can download most common email fields, like subject, from, to and others using following approach - it is much faster, but doesn't download entire email message and attachments:
