Python Question

a simple smtp server

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.

Answer

Take a look at this SMTP sink server:

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():
    foo = EmlServer(('localhost', 25), None)
    try:
        asyncore.loop()
    except KeyboardInterrupt:
        pass


if __name__ == '__main__':
    run()

It uses smtpd.SMTPServer to dump emails to files.
