Djangoとメールサーバ

簡易なSMTPDを作った。
appname/management/commands/smtpd.py

class Command(BaseCommand):
    def handle(self, *args, **options):
        daemon_kwargs = {}
        daemon_kwargs['out_log'] = options.get('outlog', 'smtp_out.log')
        daemon_kwargs['err_log'] = options.get('errlog', 'smtp_err.log')
        from django.utils.daemonize import become_daemon
        become_daemon(**daemon_kwargs)

        foo = MySMTPServer((settings.EMAIL_HOST, settings.EMAIL_PORT),
                (settings.PARENT_SMTP_HOST, settings.PARENT_SMTP_PORT))
        try:
            asyncore.loop()
        except KeyboardInterrupt:
            pass
class MySMTPServer(smtpd.SMTPServer):
    def process_message(self, peer, mailfrom, rcpttos, data):
        """ なんか素敵なことをする """

たった1行でDaemon化できるのが素敵。
