匿名发送邮件

前言：前两天分享了一下邮件的发送，但是存在的问题也很明显，首先是发送需要经过163或QQ邮箱服务器，而且不是真正的匿名，还是能够收到回复信息，其次如果系统运行在内网，限制163等，则邮件会发送失败！

于是，今天分享一个真正意义上的匿名发送(只能在Linux下运行，后面还要配置文件.....)
惯例，先上代码：

from email.header import Header
from email.mime.text import MIMEText
from email.utils import parseaddr, formataddr
import smtplib

class MailNoReply(object):
    def __FormatAddress(self, text):
        name, addr = parseaddr(text)
        return formataddr((Header(name, 'utf8').encode(), addr))

    def SendOneMail(self, sender, receiver, subject, content):
        '''
        利用本地sendmail服务发一封信
        :param sender: [string] 发信人地址 [email protected] 格式，可杜撰
        :param receiver: [string] 收信人地址 [email protected] 格式，需真实存在
        :param subject: [string] 邮件主题
        :param content: [string] 邮件内容
        :return: True/False 成功/失败
        '''
        try:
            message = MIMEText(content, 'plain', 'utf8')
            message['From'] = self.__FormatAddress('凌晨起床敲代码（随便写） <%s>' % sender)
            message['To'] = self.__FormatAddress('收件人名称（随便写） <%s>' % receiver)
            message['Subject'] = Header(subject, 'utf8').encode()

            smtpObj = smtplib.SMTP('localhost')
            smtpObj.sendmail(sender, [receiver], message.as_string())
            return True
        except smtplib.SMTPException as e:
            return False

if __name__ == "__main__":
    from datetime import datetime
    import random
    random_password = ''.join(str(i) for i in random.sample(range(0, 9), 6))
    email = "[email protected]"
    foo = MailNoReply()
    foo.SendOneMail('[email protected]', email, '密码重置',
    '亲爱的客户,您于%s发起密码重置，新密码为%s，如非本人操作请速联系管理员!' % (datetime.now().strftime('%Y-%m-%d %H:%M:%S'), random_password))

前提是需要配置sendmail：

ubuntu

sudo apt-get install sendmail sendmail-cf
sudo apt-get install mailutils
修改/etc/mail/sendmail.mc中DAEMON_OPTIONS(Family=inet, Name=MTA-v4, Port=smtp, Addr=127.0.0.1')dnl的127.0.0.1为0.0.0.0
sudo m4 sendmail.mc > sendmail.cf
把/etc/hosts中“127.0.0.1 localhost.localdomain localhost 主机名称”保留其他注掉
用echo “邮件正文” | mail -s 邮件主题 [email protected] -a From [email protected]测试一把

centos

sudo yum install -y sendmail sendmail-cf
sudo yum install mailx
修改/etc/mail/sendmail.mc中DAEMON_OPTIONS(Port=smtp,Addr=127.0.0.1, Name=MTA')dnl的127.0.0.1为0.0.0.0
sudo m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf
sudo service sendmail start [ centos7 --> systemctl start sendmail.service ]
用echo “邮件正文” | mailx -s 邮件主题 [email protected] -r [email protected]测试一把
用python脚本本机测试一把
