答案1
您从远程邮件服务器收到的错误消息是：
主机 smtp.terra.com.br[208.84.244.140] 说：450 4.1.8：发件人地址被拒绝：未找到域（回复 MAIL FROM 命令）
这意味着从地址被他们拒绝，因为该域上的 DNS 查找失败。
sales.intra我找到的任何 DNS 服务器上似乎都无法解析有问题的域名。
为了使其工作，您要么需要sales.intra在公共 DNS 中进行解析，要么将 FROM 地址更改为可以解析的地址。
有效的电子邮件是在本地发送的，而不是发送到远程服务器。您的本地服务器不会检查发件人地址是否为有效且可用的域，因此它继续处理电子邮件。
