SMTP（Simple Mail Transfer Protocol）即簡單郵件傳輸協議,它是一組用於由源地址到目的地址傳送郵件的規則，由它來控制信件的中轉方式
python的smtplib提供了一種很方便的途徑傳送電子郵件。它對smtp協議進行了簡單的封裝。

Python建立 SMTP 物件語法:
　　import smtplib
　　smtpObj = smtplib.SMTP( [host [, port [, local_hostname]]] )


引數說明：
　　host: SMTP 伺服器主機。 你可以指定主機的ip地址或者域名如: runoob.com，這個是可選引數。
　　port: 如果你提供了 host 引數, 你需要指定 SMTP 服務使用的埠號，一般情況下 SMTP 埠號為25。
　　local_hostname: 如果 SMTP 在你的本機上，你只需要指定伺服器地址為 localhost 即可。

Python SMTP 物件使用 sendmail 方法傳送郵件，語法如下:
　　SMTP.sendmail(from_addr, to_addrs, msg[, mail_options, rcpt_options]


引數說明：
　　from_addr: 郵件傳送者地址。
　　to_addrs: 字串列表，郵件傳送地址。
　　msg: 傳送訊息

 

# 使用163郵箱給自己發郵件資訊

import smtplib
from email.mime.text import MIMEText
from email.header import Header

mail_host = "smtp.163.com"
mail_user = "aaaaaa@163.com"
mail_pass = "aaaaaa"

sender = "aaaaa@163.com"
receivers = ["aaaaaa@163.com"]

message = MIMEText("python 郵件測試","plain","utf-8")
message["From"] = Header("ceshi","utf-8")
message["To"] = Header("CESHI","UTF-8")

subject = "python semp email ceshi ...."
message["Subject"] = Header(subject,"utf-8")

try:
    smtpOBJ = smtplib.SMTP()
    smtpOBJ.connect(mail_host, 25)
    smtpOBJ.login(mail_user,mail_pass)
    smtpOBJ.sendmail(sender,receivers,message.as_string())
except smtplib.SMTPException:
    print("error")

　　

# 使用163郵箱傳送資訊，帶附件

message["To"] = Header("ni","utf-8")
subject = "python smtp text, 附件"
message["Subject"] = Header("subject","utf-8")

message.attach(MIMEText('這是菜鳥教程Python 郵件傳送測試……', 'plain', 'utf-8'))

att1 = MIMEText(open("tt.yaml","r").read(),"base64","utf-8")
att1["Content-Type"] = "application/octet-stream"
att1["Content-Disposition"] = 'attachment; filename="tt.yaml"'
message.attach(att1)

try:
    smtpOBJ = smtplib.SMTP()
    smtpOBJ.connect(mail_host, 25)
    smtpOBJ.login(mail_user,mail_pass)
    smtpOBJ.sendmail(sender,receivers,message.as_string())
except smtplib.SMTPException:
    print("error")

在 HTML 文字中新增圖片
郵件的 HTML 文字中一般郵件服務商新增外鏈是無效的，正確新增突破的例項如下所示：

import smtplib
from email.mime.image import MIMEImage
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.header import Header

mail_host = "smtp.163.com"
mail_user = "15800220134@163.com"
mail_pass = "abc115698"

sender = "15800220134@163.com"
receivers = ["15800220134@163.com"]

msgRoot = MIMEMultipart("related")
msgRoot["From"] = Header("wo")
msgRoot["To"] = Header("ni")
subject = "Python SMTP 郵件測試,html + 圖片"
msgRoot["Subject"] = Header(subject,"utf-8")

msgAlternative = MIMEMultipart("alternative")
msgRoot.attach(msgAlternative)

mail_msg = """
<p>Python 郵件傳送測試...</p>
<p><a href="http://www.runoob.com">菜鳥教程連結</a></p>
<p>圖片演示：</p>
<p><img src="cid:image1"></p>
"""
msgAlternative.attach(MIMEText(mail_msg, 'html', 'utf-8'))

fb = open("1111.jpg","rb")
msgImage = MIMEImage(fb.read())
fb.close()

msgImage.add_header('Content-ID', '<image1>')
msgRoot.attach(msgImage)

try:
    smtpOBJ = smtplib.SMTP()
    smtpOBJ.connect(mail_host, 25)
    smtpOBJ.login(mail_user,mail_pass)
    smtpOBJ.sendmail(sender,receivers,msgRoot.as_string())
except smtplib.SMTPException:
    print("error")

　　

# 驗證開通郵箱的smtp協議的授權碼，並驗證登入

驗證程式碼：

import smtplib
from email.mime.text import MIMEText

server = smtplib.SMTP("smtp.163.com",25)
server.login("aaaaaa@163.com","aaaaaa")
MSG = MIMEText("hello,send by python..","plain","utf-8")
server.sendmail("aaaaaa@163.com",["aaaaaaa@163.com"],MSG.as_string())
