我正在编写一个订阅列表程序，可以将电子邮件发送到大量地址列表。我已设法使用自定义“回复”字段设置外发邮件，如下所示：
mail.ReplyToList.Add("reply-to-me@mydomain.com");
这很好用。但我还想要处理的是人们设置度假消息或其他自动应答器。现在，这些回复将转到“回复”地址。我想为自动回复设置一个不同的地址，比如“autoresponder@mydomain.com”。我知道这是可能的，因为像Yahoo Groups这样的讨论列表提供商设法拦截那些非常好的。但是如何？
编辑：这是Yahoo邮件标头的（编辑）示例。此电子邮件来自Yahoo服务器，发送至recipient@domain.com，回复发送至sender@domain.com ...但自动回复/离开办公室消息不 go发送至sender@domain.com;我的猜测是他们去了标题顶部附近的“返回路径”地址（sentto-74624151-351-1308558348-recipient=domain.com@returns.groups.yahoo.com）。但是，如何在发送邮件时将该行添加到SMTP标头？

通常这是通过在返回时处理邮件来完成的 - 例如，Outlook规则，或者其他什么，SMTP不区分自动响应者和正确的电子邮件。

对不起，朋友。我不认为SMTP支持这种类型的请求。雅虎很可能通过过滤器在他们的电子邮件服务器中实现这一点，如评论中所述。
