WCF 已超过传入消息(65536)的最大消息大小配额

我已经把客户端的app.config的相应字段设成最大值，为什么还是不行？
设置如下：
 <binding name="WSHttpBinding_ISettingServ" closeTimeout="00:01:00"
                    openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00"
                    bypassProxyOnLocal="true" transactionFlow="true" hostNameComparisonMode="StrongWildcard"
                    maxBufferPoolSize="2147483647" maxReceivedMessageSize="214748364"
                    messageEncoding="Text" textEncoding="utf-8" useDefaultWebProxy="true"
                    allowCookies="false">
<readerQuotas maxDepth="655360" maxStringContentLength="214748364" maxArrayLength="214748364"
                        maxBytesPerRead="655360" maxNameTableCharCount="655360" />
                    <reliableSession ordered="true" inactivityTimeout="00:10:00"
                        enabled="false" />
                    <security mode="None">

                    </security>
                </binding>望各位高手指点。
