我正在设置一个使用 Ciphermail 作为 RelayHost 的邮件服务器 [postfix]。通过设置，我可以将邮件发送到外部域，但是当我从外部域回复时，我收到了以下错误。

在此处输入图像描述

unverified_recipient_reject_code = ${djigzo_unverified_recipient_reject_code}
当我从架构中删除中继主机 [ciphermail] 时，我能够接收来自外部域的邮件。

请提出答案。

您似乎已启用“拒绝未经验证的收件人”。450 错误消息报告无法验证收件人地址。CipherMail 的默认 Postfix 配置是 Postfix 将用作存储和转发服务器，并且没有本地邮箱。但是，您已将 mydestination（通过设置 djigzo_mydestination 间接设置）配置为在本地处理 svitsolutions.in 的邮件，但您也将 relay_domains（通过设置 djigzo_relay_domains 间接设置）配置为 svitsolutions.in。

使用当前配置，发送到 svitsolutions.in 的电子邮件将由本地传输处理（然后将在本地存储电子邮件）。然而，在默认的 Postfix master.cf 配置中，本地传输被禁用，因为在默认配置中，电子邮件不应存储在本地。由于本地传输不可用，收件人验证将失败。

如果您想在本地存储电子邮件，您应该重新启用本地传输（请参阅 main.cf 和 master.cf）并确保本地用户可用。如果您不想将邮件本地存储在系统上而仅充当中继服务器，请将 djigzo_mydestination 和 mydestination 设置为空值。
