< 强/ 强> 背后的想法
我试图从程序上追踪无法执行的信息, 所以我必须找到一个方法, 找出来自拒绝特定信息的目标 SMTP 服务器的回复 。
现在我想到了简单记住 Message-ID SMTP头值, 并分析此ID 的邮件 。
我试图查看"https://learn.microsoft.com/en-us/dotnet/api/system.net.mail.mailmessage.mailsage#System_Net_Mail_MailMessage_headers" rel="无跟踪 noreferr"\code> Headers 收藏 ,但是我没有发现任何 Message-ID 。

根据Message-ID 。
到目前为止,我的所有例子都发挥了作用,因此,这似乎解决了我的问题。

您可以在发送电子邮件前添加您自己的邮件代号 。 我使用下一个代码 :
Guid id = Guid.NewGuid(); //Save the id in your database
mensajeEmail.Headers.Add("Message-Id", String.Format("<{0}@{1}>",id.ToString(),"mail.example.com"));
注:对于下载信息,我使用 OpenPop.Net ,我检查了 messesage.headers.InReplyTo 属性,还有消息 id 已发送。
为.Net 和 SMTP 客户端使用 MailKit 图书馆。
我尝试了另一个解决方案, 以获取 SMTP 客户端发送的信件的 ID, 以追踪任何回信 。
在发送信件前,在信件信头中添加隐藏的 ID 属性,

Now continue and send your message,
Wait about 10 Seconds, Then you will use the IMAP Client to get your Sent folder and for each message in your folder,
loop over the message headers and check if anyone of them is ==messageIdentity, now you catch your
sent message successfully and get any information about it you wand like ID etc...
