Python sends Mail via SMTP

Python version: Python3.5.2

Brief introduction

SMTP is the protocol that sends messages, and Python's built-in support for SMTP can send plain text messages, HTML messages, and messages with attachments.

Python supports SMTP support with smtplib and email two modules, email is responsible for structuring the mail, Smtplib is responsible for sending mail.

I use QQ mailbox to complete this experiment, first should configure their own mailbox to enable the SMTP function, the following steps:

Login to the homepage of the QQ mailbox, find the setting function:

Go to Settings, switch to Account tab:

Drop-down to find the following options and enable the SMTP feature:

Upon successful activation, an authorization code is generated to log on to the SMTP server. This license code is not unique, you can click to forget the words generated again.

The experimental source is as follows

__author__ = "lance#" #-*-coding = utf-8-*-from Email import encodersfrom email.header import Headerfrom Email.mime.text Import mimetextfrom email.utils import parseaddr, Formataddrimport smtplibdef _format_addr (s): name, addr = Parseaddr ( s) return formataddr (Header (name, ' Utf-8 '). Encode (), addr)) from_addr = ' [email protected] ' password = ' Your Authorization code ' TO_A DDR = ' [email protected] ' smtp_server = ' smtp.qq.com ' #要发送的消息SendMsg = ' This is SMTP test. ' #构造一个 Mimetext Object msg = Mimetext (sendmsg, ' plain ', ' utf-8 ') #依次填充对象的各个选项msg [' from '] = _format_addr (' Python <%s> '% fr OM_ADDR) msg["to" = _format_addr (' User <%s> '% to_addr) msg[' Subject '] = Header (' This is SMTP test. ', ' Utf-8 '). encod E () #构造 the SMTP server, the SMTP port for the QQ mailbox is 465 and the SSL encryption protocol server = Smtplib. Smtp_ssl (Smtp_server, 465) #启用该选项, can print out all the information that interacts with the SMTP server Server.set_debuglevel (1) server.login (from_addr, password) # Send mail, here to_addr can be a list, can send to multiple people server.sendmail (FROM_ADDR, [to_addr], msg.as_string ()) #退出 SMTP Server Server.quit ()

The mailbox that receives the message can be set to the same as the sender's address, so that when the program finishes running, its mailbox can receive the message that was just sent.
