通过Outlook发送电子邮件时PostFix问题

我也有Relay访问被拒绝的问题，这真的让我感到不安。 我可以通过网络邮件正常发送和接收。

但是，当我在[B] Outlook [/ B]上配置电子邮件而不使用身份验证发送电子邮件时出现以下错误：

错误：NOQUEUE：拒绝：未知[MyIPaddress]的RCPT：554 5.7.1：拒绝中继访问; from = to = proto = ESMTP helo =

如果我使用My Outgoing服务器需要身份验证，我会得到：

登录接收邮件服务器（POP3）：您的电子邮件服务器拒绝使用安全密码验证（SPA）登录。在“帐户设置”中验证帐户属性。发送测试电子邮件：服务器不支持此客户端支持的任何身份验证方法。
