一般发邮件方法
我以前在通过Python实现自动化邮件功能的时候是这样的：
<pre class="ql-align-justify" style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">import smtplib
from email.mime.text import MIMEText
from email.header import Header
发送邮箱服务器
smtpserver = 'smtp.sina.com'
发送邮箱用户/密码
user = '[email protected]'
password = '123456'
发送邮箱
sender = '[email protected]'
接收邮箱
receiver = '[email protected]'
发送邮件主题
subject = 'Python email test'
编写HTML类型的邮件正文
msg = MIMEText('<html><h1>你好！</h1></html>','html','utf-8')
msg['Subject'] = Header(subject, 'utf-8')
连接发送邮件
smtp = smtplib.SMTP()
smtp.connect(smtpserver)
smtp.login(user, password)
smtp.sendmail(sender, receiver, msg.as_string())
smtp.quit()
</pre>
其实，这段代码也并不复杂，只要你理解使用过邮箱发送邮件，那么以下问题是你必须要考虑的：
你登录的邮箱帐号/密码
对方的邮箱帐号
邮件内容（标题，正文，附件）
邮箱服务器（SMTP.xxx.com/pop3.xxx.com）
yagmail 实现发邮件
yagmail 可以更简单的来实现自动发邮件功能。
github项目地址: https://github.com/kootenpv/yagmail
Github大牛封装Python代码，如今实现自动发送邮件只需三行代码
代码开源，解释如下：
<pre class="ql-align-justify" style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">yag = SMTP(args.user, args.password)
yag.send(to=args.to, subject=args.subject, contents=args.contents, attachments=args.attachments)
</pre>
安装：
<pre class="ql-align-justify" style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">pip install yagmail
</pre>
简单例子：
<pre class="ql-align-justify" style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">import yagmail
链接邮箱服务器
yag = yagmail.SMTP( user="[email protected]", password="1234", host='smtp.126.com')
邮箱正文
contents = ['This is the body, and here is just text http://somedomain/image.png',
'You can find an audio file attached.', '/local/path/song.mp3']
发送邮件
yag.send('[email protected]', 'subject', contents)
</pre>
给多个用户发邮件：
只需要将接收邮箱 变成一个list即可。
<pre class="ql-align-justify" style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"># 发送邮件
yag.send(['[email protected]','[email protected]','[email protected]'], 'subject', contents)
</pre>
发送附件，只要添加一个附件列表就可以了。
<pre class="ql-align-justify" style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"># 发送邮件
yag.send('[email protected]', '发送附件', contents, ["d://log.txt","d://baidu_img.jpg"])
</pre>

抄送
<pre class="ql-align-justify" style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"># 邮箱正文 文本及附件
contents = ['This is the body, and here is just text http://somedomain/image.png',
'You can find an audio file attached.', '/local/path/song.mp3', '测试邮件', 'test.html', 'logo.jpg',
'yagmal_test.txt']
发送邮件
yag.send(to='[email protected]', cc='[email protected]', subject='发送附件', contents=contents)
</pre>
真是简单，谁做得这个包，我真想给一个么么哒
