[Twisted-Python] SMTP with authentication
Hi, I am new to twisted but google and the Oreilly book have failed me. I am trying to create a client to send to a smtp server. All the examples that I have found only work if your SMTP server does not require authentication. I am guessing that I need to use http://twistedmatrix.com/documents/current/api/twisted.mail.smtp.ESMTPSender... Unfortunately, I can find no examples that use it. I did find something from 2004 http://twistedmatrix.com/pipermail/twisted-python/2004-April/007433.html That is prior to the commit for ESMTPSenderFactory http://twistedmatrix.com/pipermail/twisted-commits/2004-July/011608.html Thanks -- Alvin

This changed ESMTPSenderFactory, but authentication was supported before this commit. Give the code at the previous URL a try and post again if you run into problems. Jean-Paul
I modified this example http://twistedmatrix.com/projects/mail/documentation/tutorial/smtpclient/smt...

You broke the example. Try this, hopefully it is clearly what is happening: import StringIO from twisted.application import service application = service.Application("SMTP Client Tutorial") from twisted.application import internet from twisted.python import log from twisted.internet import defer, reactor from twisted.mail import smtp mailFrom = "from@example.com" mailTo = ["to@example.com",] mail = StringIO.StringIO("""Date: Fri, 3 Nov 2006 230:14:39 +0000 From: from@example.com To: to@example.com Subject: Tutorate! Hello, how are you, goodbye. """) whenDone = defer.Deferred() def send(r): print "message sent:", r whenDone.addCallbacks(sent, log.err) def done(d): from twisted.internet import reactor reactor.callLater(1, reactor.stop) whenDone.addBoth(done) sender = smtp.ESMTPSenderFactory( 'YOURUSERNAME', 'YOURPASSWORD', mailFrom, mailTo, mail, whenDone, ) smtpClientService = internet.TCPClient('YOURSERVER', 25, sender) smtpClientService.setServiceParent(application)
Thanks!! That worked great. minor typo def sent(r): print "message sent:", r A question. In Phil Mayer's example and Marcin Kasperski's example, it seems like there is a new tcp/ip connection made for each email. Suppose, I want to send multiple emails to the same smtp server. How would that work? Thanks Alvin * *On 11/4/06, Phil Mayers <p.mayers@imperial.ac.uk> wrote:
