尝试使用该文档中的短语：http://www.limilabs.com/blog/imap-search-requires-parentheses

    private void SearchFromTest()
    {

        try
        {
            var _selectedMailBox = "INBOX";
            var _searchWithEmailFrom = "email@domain.com";
            using (var _clientImap4 = new Imap4Client())
            {

                _clientImap4.ConnectSsl(_imapServerAddress, _imapPort);
                //_clientImap4.Connect(_mailServer.address, _mailServer.port);

                _clientImap4.Login(_imapLogin, _imapPassword); // Efetua login e carrega as MailBox da conta.
                //_clientImap4.LoginFast(_imapLogin, _imapPassword); // Efetua login e não carrega as MailBox da conta.

                var _mailBox = _clientImap4.SelectMailbox(_selectedMailBox);

                // A0001 SEARCH CHARSET utf-8 BODY "somestring" OR TO "someone@me.com" FROM "someone@me.com"
                var searchPhrase = "CHARSET utf-8 FROM \"" + _searchWithEmailFrom +  "\"";
                foreach (var messageId in _mailBox.Search(searchPhrase).AsEnumerable())
                {
                    var message = _mailBox.Fetch.Message(messageId);
                    var _imapMessage = Parser.ParseMessage(message);
                }

                _clientImap4.Disconnect();
            }

            Assert.IsTrue(true);
        }
        catch (Exception e)
        {
            Assert.Fail("Don't work.", e);
        }

    }
