Question

我尝试以尽可能少的安全性连接到邮件服务器。我使用这个邮件服务器在我的本地机器上进行测试。我想配置我的WSO2 ESB实例，以便以正确的方式解析邮件消息。此时我不想购买或创建SSL证书。

当我使用mailto transport创建代理服务时，我发现它没有连接，因为我的ESB会说SSL而我的邮件服务器会说纯文本。在wso2-esb-errors.log中，我发现此错误

javax.net.ssl.SSLException：无法识别的SSL消息，明文连接？

我已经尝试了不同的方法将我的代理切换到明文模式，其中列出了参数：

https://docs.wso2.com/display/ESB481/MailTo+Transport

https://javamail.java.net/nonav/docs/api/com/sun/mail/pop3/package-summary.html

我无法弄清楚如何禁用SSL层。所以，请帮忙！

当前代理配置如下：

<?xml version="1.0" encoding="UTF-8"?>
<proxy xmlns="http://ws.apache.org/ns/synapse"
   name="mail_local_monitor"
   transports="mailto"
   statistics="disable"
   trace="disable"
   startOnLoad="true">
   <target>
      <inSequence>
         <property name="OUT_ONLY" value="true" scope="default" type="STRING"/>
         <log level="full"/>
      </inSequence>
   </target>
   <parameter name="mail.pop3.ssl.enable">false</parameter>
   <parameter name="mail.pop3.host">127.0.0.1</parameter>
   <parameter name="transport.PollInterval">5</parameter>
   <parameter name="mail.pop3.starttls.enable">false</parameter>
   <parameter name="mail.pop3.password">12345</parameter>
   <parameter name="mail.transport.protocol">pop3</parameter>
   <parameter name="mail.pop3.user">esb@mail.local</parameter>
   <parameter name="transport.mail.ContentType">text/plain</parameter>
   <parameter name="mail.pop3.port">110</parameter>
   <parameter name="transport.mail.Address">esb@mail.local</parameter>
   <parameter name="transport.mail.Protocol">pop3</parameter>
   <description/>
</proxy>

完整错误输出：
