Example of sending mail using SMTP in Python

One, SMTP sends mail

Here the Python script is to log 126 of SMTP to send mail to the QQ mailbox.
QQ mailbox use is encrypted stmp, need to encrypt version of children's shoes please pay attention to the subsequent updates.
TIPS: My local environment is a MAC system, the Windows environment needs to modify the corresponding character encoding.

#!/usr/bin/env python # -*- coding: utf-8 -*-import smtplib   Import  email.encoders From email.mime.text import mimetext from email.mime.multipart  Import mimemultipart from email.mime.base import mimebase Import getpass # Build  a new attach instance Msg = mimemultipart () # mail configuration Mail_

Two, SMTP (SSL) Send mail

Here need to pay attention to the use of QQ mailbox (SMTL over SSL), you need to first in its web client background to open the Smtp/pop service, and set up QQ mailbox independent password as SMTP login password, so in the use of MUA will not be reported authentication Failed's mistake.
QQ Mailbox POP3 Port: 995 SMTP Port: 587
Password use QQ mailbox Independent password
