Python发邮件之邮件头、附件及包格式最近研究用python发送Email的问题，对email header等方面的编码颇有心得，着笔记录下，以备后查。用python发的整个邮件，每个元素都以/r/n结束（当然如果内容里有/r/n如何就不太清楚了）。其邮件内容都是被一个大的boundary包起来的，Content-Type为multipart/mixed。 header部分，大致有MIME-Version、From、To、Subject等，看情况而定（事实上，我观察注意阅读详情

EOP对于邮件头的迷之操作邮件系统的Journaling （归档）是一个重要的合规应用，而且在大多数场合可以替代邮件备份，所以是否正常运作非常重要。最近遇到O365发到本地邮箱的邮件不再归档（Journaling）的问题，但本地邮箱的归档功能依然正常。基本配置是：本地Exchange邮箱数据库上启用了Journaling设置（微软称为StandardJournaling，对比可以更精细化可以为特定邮箱设置归档的PremiumJournaling），指定第三方邮件地址为Journal邮箱。云端O365上并未配置... 阅读详情

老大你莫豆我了，怪我没有说清楚，我想说的是：用pop3协议收到到邮件后我如何把邮件头分解开，以便显示。例如：

我现在要把这封邮件的邮件头分解开，什么收件人，发件人，附件......。是以什么样的关键字来定位，还是有别的好方法。还有附件怎么处理!!

一、SMTP协议简介

1、客户端通过服务器的25端口建立TCP/IP连接

服务器端： 220 server.com Simple Mail Transfer Service Ready

2、客户端使用“HELO”命令标识发件人

客户端：HELO server.com
服务器端：250 server.com
3、客户端发送MAIL命令，服务器端以OK作为响应表明准备接收

客户端： MAIL FROM: <A@B.com>
服务器端： 250 OK
4、客户端发送RCPT命令标识收件人，服务器端回应是否愿意为收件人接受邮件

客户端：RCPT TO: <d@e.com>
服务器端：250 OK
5、协商结束后用命令DATA发送发送邮件

客户端：DATA
服务器端：354 Start mail input: end with <CRLF>.<CRLF>
6、客户端以.表示结束输入内容一起发送出去

客户端：Subject: <CRLF>
内容<CRLF>
.<CRLF>

7、客户端用QUIT命令退出。

客户端：QUIT
服务器端：250 server.com closing transmission channel
二、SMTP客户端程序代码：

1、用VS.NET新建一个C# WINDOWS应用程序项目，命名为SMTP。

2、在窗体上添加控件：

一个按钮：设置属性name->btnsend；text->发送

六个标签：分别提示服务器地址、发件人、收件人、主题、内容以及发送记录

五个文本框：服务器地址txtsmtp、发件人txtfrom、收件人txtto、主题txtsub、内容txtmsg对应相应的标签放置。

一个列表框：lstlog

3、在程序开头添加以下名字空间：

using System.Data;

using System.Net;

using System.Net.Sockets;

using System.IO;

4、在 btnsend_Click 函数中添加如下代码：

点击查看
保存工程并编译，邮件发送程序就编制成功了，我们还可以进一步改造该函数，制作一个SMTP类，将其应用于自己的软件。
private void btnsend_Click(object sender, System.EventArgs e)

{

// 将鼠标形状改为漏斗状

Cursor cr = Cursor.Current;

Cursor.Current = Cursors.WaitCursor;

//定义变量

string Data;

byte[] szData;

string CRLF = "\r\n";

//创建与服务器25端口的连接

TcpClient SmtpServ = new TcpClient(txtsmtp.Text,25);

lstlog.Items.Clear();

//显示服务器初始信息

NetworkStream NetStrm = SmtpServ.GetStream();

StreamReader RdStrm= new StreamReader(SmtpServ.GetStream());

lstlog.Items.Add(RdStrm.ReadLine());

//标志发件人

Data = "HELO server " + CRLF;

szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());

NetStrm.Write(szData,0,szData.Length);

lstlog.Items.Add(RdStrm.ReadLine());

//标志发件人

Data = "MAIL FROM: " + "<" + txtfrom.Text + ">" + CRLF;

szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());

NetStrm.Write(szData,0,szData.Length);

lstlog.Items.Add(RdStrm.ReadLine(

// 标志收件人

Data = "RCPT TO: " + "<" + txtto.Text + ">" + CRLF;

szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());

NetStrm.Write(szData,0,szData.Length);

lstlog.Items.Add(RdStrm.ReadLine());

//准备发送内容

Data = "DATA " + CRLF;

szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());

NetStrm.Write(szData,0,szData.Length);

lstlog.Items.Add(RdStrm.ReadLine());

//发送主题

Data = "SUBJECT: " + txtsub.Text + CRLF ;

//发送内容

Data = Data+ txtmsg.Text + CRLF ;

//结束发送

Data = Data+ "." + CRLF;

szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());

NetStrm.Write(szData,0,szData.Length);

lstlog.Items.Add(RdStrm.ReadLine());

//退出

Data = "QUIT " + CRLF;

szData = System.Text.Encoding.ASCII.GetBytes(Data.ToCharArray());

NetStrm.Write(szData,0,szData.Length);

lstlog.Items.Add(RdStrm.ReadLine());

//关闭连接

NetStrm.Close();

RdStrm.Close();

lstlog.Items.Add("连接关闭");

lstlog.Items.Add("发送成功");

//将鼠标恢复箭头状

Cursor.Current = cr;

}

诶～
