Use Imap.PeekMessageByUID instead of Imap.GetMessageByUID when you download the emails.

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

    imap.SelectInbox();
    List<long> uidList = imap.Search(Flag.Unseen);
    foreach (long uid in uidList)
    {
        IMail email = new MailBuilder()
            .CreateFromEml(imap.PeekMessageByUID(uid)); //<-- Peek

        string subject = email.Subject;
    }
    imap.Close();
}
