我试图build立一个Postfix，Dovecot，Spamassassin电子邮件堆栈，并安装和configuration了所有东西。
但是，每次尝试使用我的客户端连接到我的服务器时，都无法连接到传出服务器（configuration传入时没有问题）。 我已经尝试了Thunderbird（在我的电脑上）和Bluemail（在我的电话上）。
当我尝试连接到传出服务器时， mail.log显示两行：
Aug 11 12:39:07 pyrosoftsolutions postfix/smtpd[13039]: lost connection after EHLO from 60.216.208.46.dyn.plus.net[46.208.216.60] Aug 11 12:39:07 pyrosoftsolutions postfix/smtpd[13039]: disconnect from 60.216.208.46.dyn.plus.net[46.208.216.60] ehlo=1 commands=1
我已经尝试连接端口587有和没有身份validation。
我的netstat显示postfix实际上正在侦听正确的端口：

这是我的master.cf文件：

而我的ufw status verbose ：

奇怪的是，但是，我可以telnet端口587内部和外部没有问题。
有什么build议？
