一个简单的 SMTP 服务器(在 Python 中)

问题描述

您能否推荐一个简单的 SMTP 服务器,它具有非常基本的 API(我的意思是非常基本的,读取、写入、删除电子邮件),可以在 linux 机器上运行?我只需要把邮件的症结转成XML格式,然后FTP到另一台机器上.

Could you please suggest a simple SMTP server with the very basic APIs (by very basic I mean, to read, write, delete email), that could be run on a linux box? I just need to convert the crux of the email into XML format and FTP it to another machine.


解决方案

看看这个 SMTP sink服务器:

from __future__ import print_function
from datetime import datetime
import asyncore
from smtpd import SMTPServer

class EmlServer(SMTPServer):
    no = 0
    def process_message(self, peer, mailfrom, rcpttos, data):
        filename = '%s-%d.eml' % (datetime.now().strftime('%Y%m%d%H%M%S'),
                self.no)
        f = open(filename, 'w')
        f.write(data)
        f.close
        print('%s saved.' % filename)
        self.no += 1


def run():
    # start the smtp server on localhost:1025
    foo = EmlServer(('localhost', 1025), None)
    try:
        asyncore.loop()
    except KeyboardInterrupt:
        pass


if __name__ == '__main__':
    run()

它使用 smtpd.SMTPServer 将电子邮件转储到文件中.

It uses smtpd.SMTPServer to dump emails to files.
