python_smtlib_email

基于python3+smtlib库，发送email

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

# 第三方 SMTP 服务
mail_host="smtp.exmail.qq.com"  #设置服务器
mail_user="[e-mail]"    #用户名
mail_pass="xxxxx"            #口令

sender = '[e-mail]'
receivers = ['[e-mail]']

message = MIMEText('Python 邮件发送测试...', 'plain', 'utf-8')
message['From'] = Header("Python邮件", 'utf-8')
message['To'] =  Header("测试", 'utf-8')

subject = 'Python SMTP 邮件测试'
message['Subject'] = Header(subject, 'utf-8')

try:
    smtpObj = smtplib.SMTP_SSL(mail_host, 465)
    smtpObj.login(mail_user,mail_pass)
    smtpObj.sendmail(sender, receivers, message.as_string())
    print ("邮件发送成功")
except smtplib.SMTPException:
    print ("Error: 无法发送邮件")
