< h2 id = "iredapd" > iRedAPD< / h2 >
< p > iRedAPD 插件 < code > reject_sender_login_mismatch< / code > 会检测伪造的发件人地址。如果发件人
的域名在你的服务器托管,并且邮件不是经由 SMTP 验证发送的,就会被认为是伪造的
发件人。这种情况下 iRedAPD 会直接拒收邮件(拒收提示信息为:< code > Policy rejection
not logged in< / code > ),因此需要在 iRedAPD 里放行将该收件人邮件地址。如果邮件是由
固定的内部网络设备发送(例如,打印机、传真机),可以直接放行 IP 地址。< / p >
< ul >
< li > 放行发件人邮件地址 < code > user@example.com< / code > ,请在 < code > /opt/iredapd/settings.py< / code > 里
加以下参数:< / li >
< / ul >
< pre > < code > ALLOWED_FORGED_SENDERS = ['user@example.com']
< / code > < / pre >

< li > 放行发件人 IP 地址或网段,例如, < code > 192.168.0.1< / code > 和 < code > 192.168.1.0/24< / code > ,请在
< code > /opt/iredapd/settings.py< / code > 里加以下参数:< / li >
