Postfix 邮件服务器搭建

Question

Postfix 邮件服务器搭建，邮件服务器最好绑定域名，不然会被屏蔽

安装

sudo apt-get install mailutils

Add your domain to the config files, so others can't abuse your mailsystem:

postconf -e "myorigin = example.com"

Add your hostname (computer name). (Use command "hostname" at the command-line to display your hostname if not sure.)

postconf -e "myhostname=server1.example.com"

Now add the domain names that your system will handle.

postconf -e "relay_domains = example.com, example2.com, example3.com"

重启：

sudo service postfix restart

配置 postfix

sudo dpkg-reconfigure postfix

测试发送：

telnet localhost 25

测试：

mail from:<you@youremail.com>
rcpt to:<user@example.com>
data
To: user@example.com
From: you@youremail.com
Subject: Hey my first email
This is my first email on debian postfix after installing configuring it.
It was easy.

代码测试：

#!/usr/bin/env python
# -*- encoding: utf-8 -*-

import smtplib
from email.message import Message

class Mail:
    def __init__(self, config):
        self.__config = config
        self.__sender = self.__config['user']

    def send(self, receiver, subject, content):

        message = Message()
        message['Subject'] = subject
        message['From'] = self.__sender
        message['To'] = receiver
        message.add_header('Content-Type', 'text/html;charset=utf-8')
        message.set_payload(content)

        try:
            smtp = smtplib.SMTP()
            smtp.set_debuglevel(1)
            smtp.connect(self.__config['host'])
            smtp.sendmail(self.__sender, receiver, message.as_string())
            smtp.close()
            return True
        except Exception, error:
            print str(error)
            return False

if __name__ == '__main__':

    config = {
        'host': 'lives.ws',
        'user': 'no-reply@lives.ws',
    }

    mailer = Mail(config)
    mailer.send('twn39@163.com', 'python', 'python postfix test')
    print 'mail is send.'
