无法连接到587上的后缀

我花了很多时间在这里找相关post的答案，但无济于事。 所以这就是为什么我在这里问这个问题。

• 我有：Debian 8，Postfix，Dovecot
• 我可以用roundcube发送和接收电子邮件。
• 我可以收到雷鸟的电子邮件。
• 我不能用雷鸟发送邮件。
• 雷鸟说，它连接到服务器，但它超时，因为没有从服务器的响应。
• 我禁用了我的防火墙。
• 我不知道要在服务器名称字段中填写什么。
• 我试图发送的电子邮件最终在服务器的概念框中

我跟着https://workaround.org/ispmail/jessie

这是我目前的configuration。

postconf | grep smtpd_sasl_auth_enable：

• mod_pagespeed：安装早期版本兼容libc6 2.13（Debian Wheezy）
• 用户组和用户的成员
• 自定义邮件服务器上的未知用户
• exim4使用错误的邮件服务器主机名
• rsyslog：只logging一些消息到特定的文件

 smtpd_sasl_auth_enable = yes 

postconf | grep smtp_sasl_auth_enable：

 smtp_sasl_auth_enable = yes 

当我使用Telnet连接到端口25时，我得到了来自ehlo的以下响应

 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN 

AUTH未启用。 为什么？

当我尝试使用587上的telnet连接时，我看到一个空白的屏幕。

我没有任何线索。 希望这里有人这样做。

非常感谢。
