linux下发送邮件,我用的服务器是阿里云,向网易邮箱发邮件,因为阿里云ECS专有网络服务器禁用了25端口,所以改用了465
第一种方法:
test1.py

# coding:utf-8
import smtplib
import sys
from email.mime.text import MIMEText

mailto_list=['XXX@163.com']   #收件人邮箱列表
mail_user="XXX@163.com"       #用户名
mail_passwd="XXXXX"           #用户登录密码(第三方登录授权码)
mail_host="smtp.163.com"      #邮箱服务器
mail_postfix="163.com"        #邮箱后缀名

def send_mail(to_list,sub,content): #定义函数,参数为收件人,邮件主题,邮件内容
    print content
    me="<"+mail_user+">"

    msg=MIMEText(content,'plain')
    msg['Subject']=sub
    msg['From']=me
    msg['To']=';'.join(to_list)    #将收件人列表以“;” 形式隔开

    try:
         server = smtplib.SMTP_SSL()    #用的是SSL协议的邮箱smtp
         server.connect(mail_host,465)  #smtp 的端口号465
         print server.login(mail_user,mail_passwd)
         server.sendmail(me,to_list,msg.as_string()) #SMTP对象使用sendmail 方法发送邮件 #SMTP.sendmail(from_addr, to_addrs, msg[, mail_options, rcpt_options]
         server.close()
    except Exception, e:
        print str(e)
        return False

send_mail(mailto_list,"Long time no see",'happy new year,beautiful girl') #调用函数

第二种方法:
test2.py

#coding:utf-8
import sys
import smtplib
#import email.mime.multipart
from email.mime.text import MIMEText

server = 'smtp.163.com'
port = '465'


def send_mail(server,port,usr,pwd,msg):
    smtp = smtplib.SMTP_SSL()
    smtp.connect(server,port)
    smtp.login(usr,pwd)
    smtp.sendmail(msg['from'],msg['to'],msg.as_string())
    smtp.quit()
    print('email has send out successfully !')


if  __name__ == '__main__':
 #   msg = email.mime.multipart.MIMEMutipart()
    msg = MIMEText('beautiful girl','plain')
    msg['subject'] = 'HELLO PYTHON,ITS MY FIRST MAIL TO YOU'
    msg['From'] = '发件人邮箱@163.com'
    msg['To'] = '收件人邮箱@163.com'
    usr =  '用户名'
    pwd = '密码' (第三方授权码)
    content=' '.join(sys.argv[4:])

  send_mail(server,port,usr,pwd,msg)

这两种方法大同小异,# python test1.py 运行此文件
