[Twisted-web] HTTP POST from SMTP server

[James Brady]

Hi all,
I'm a complete Twisted newcomer, so still getting to grips with the ways
thing work..

What I'm trying to do is submit a POST request when I receive email into my
SMTP server.

At the moment, I've basically modified emailserver.tac from the examples (
http://twistedmatrix.com/projects/mail/documentation/examples/emailserver.t=
ac
)

My eomReceived message has this code added to it:
...
        client =3D getPage(url=3D'http://localhost:8080/message_event_notif=
y',
method=3D'POST',
            postdata=3Durlencode(postdata),
            headers=3D{ 'Content-Type': 'application/x-www-form-urlencoded'=
 }
)
        client.addCallback(self.success)
        client.addErrback(self.failure)
        reactor.run()

...

The POST request is received and processed as expected, and the success
method is invoked, but then the server stacktraces and halts, while the SMTP
sender client never completes. The server stacktrace:

Does anyone have any suggestions?

Thanks,
