在 WSO2 ESB 中发送电子邮件时出错

Question

您好，我正在使用 WSO2 ESB 4.7.0，

我正在尝试使用 WSO2 ESB 发送电子邮件，为此我取消了 Axis2.xml 文件中的以下行的注释，

<transportSender name=”mailto”>
<parameter name=”mail.smtp.host”>smtp.gmail.com</parameter>
<parameter name=”mail.smtp.port”>587</parameter>
<parameter name=”mail.smtp.starttls.enable”>true</parameter>
<parameter name=”mail.smtp.auth”>true</parameter>
<parameter name=”mail.smtp.user”>synapse.demo.0</parameter>
<parameter name=”mail.smtp.password”>password</parameter>
<parameter name=”mail.smtp.from”>Sender@gmail.com</parameter>
</transportSender>
<transportReceiver name=”mailto”>

并且我在 esb 中创建了一个代理。

<proxy xmlns="http://ws.apache.org/ns/synapse"
   name="mailtoproxy"
   transports="https,http"
   statistics="disable"
   trace="disable"
   startOnLoad="true">
 <target>
  <inSequence>
              <payloadFactory media-type="xml">
        <format>
           <format xmlns="">
              <sendMailResponse></sendMailResponse>
           </format>
        </format>
        <args>
           <arg value="Message Sent from the WSO2 ESB"/>
        </args>
     </payloadFactory>
     <property name="transport.mail.Format"
               value="Attachment"
               scope="axis2"
               type="STRING"/>
     <property name="AttachmentFile"
               value="Attachment.csv"
               scope="axis2"
               type="STRING"/>
     <property name="Subject"
               value="File Received"
               scope="transport"
               type="STRING"/>
<property name="OUT_ONLY" value="true" scope="default" type="STRING"/>
     <log level="full"/>
     <send>
        <endpoint>
           <address uri="mailto:receiver@gmail.com"/>
        </endpoint>
     </send>
  </inSequence>
  <outSequence>
     <send/>
  </outSequence>
  </target>
  <description/>
   </proxy>

当我向该服务发送请求时，这应该会向接收方@gmail.com发送邮件，但它在我的 ESB 服务器中显示错误，如下所示

请帮我解决这个错误。
