Mule 3.3.0 POP3连接器配置不兼容'；行不通

我正在尝试一个简单的Mule 3.3.0配置，它将下载每封电子邮件并将其传递给我的定制处理器类。一旦检索到电子邮件，它应该从gmail收件箱中删除。但这似乎不起作用。下面是我的mule-config.xml

<spring:beans>
    <spring:import resource="classpath:spring/applicationContextServices-core.xml"/>
    <spring:import resource="classpath:spring/applicationContextServices-configuration.xml"/>
    <spring:bean id="emailSender" name="emailSender" class="com.test.EmailSender"/>
    <spring:bean id="retrieveEmailProcessor" name="retrieveEmailProcessor" class="com.test.RetrieveEmailProcessor"/>
</spring:beans>


<jms:activemq-connector name="Active_MQ" specification="1.1" username="[username]" password="[password]" brokerURL="tcp://localhost:61616" validateConnections="true" doc:name="Active MQ">
    <reconnect/>
</jms:activemq-connector>

<pop3s:connector name="pop3Connector" checkFrequency="45600" deleteReadMessages="true"/>

<flow name="1_SendMessageToOwner" doc:name="1_SendMessageToOwner" doc:description="This is to confirm that your email was received successfully">
    <jms:inbound-endpoint topic="PoolMessage" connector-ref="Active_MQ" doc:name="JMS"/>
    <component doc:name="Build Email Message">
        <spring-object bean="emailSender"/>
    </component>
    <smtps:outbound-endpoint host="smtp.gmail.com" port="465" user="[username]%40gmail.com" password="[password]" from="[username]@gmail.com" responseTimeout="50000" doc:name="SMTP"/>
</flow>

<flow name="2_ReceiveConfirmation" doc:name="2_ReceiveConfirmation" doc:description="Retrieving Email">
    <pop3s:inbound-endpoint connector-ref="pop3Connector" host="pop.gmail.com" port="995" user="[username]%40gmail.com" password="[password]" responseTimeout="10000" doc:name="Pop3"/>
    <component doc:name="Process Transaction - Confirmation Message" doc:description="Recieve confirmation from member.">
        <spring-object bean="retrieveEmailProcessor"/>
    </component>
</flow>

</mule>

}


我有什么明显的遗漏吗？
提前感谢
您的骡子配置很好。

您需要检查您的Gmail配置：

设置->转发和POP/IMAP->在POP下载中：-->2。使用POP访问消息时

如果你想让你的邮件在POP连接器读取后被删除或存档，你需要选择“删除Gmail的副本”
