Hi,
I am trying to use twisted to implement a script to send the email,I got
some problem.here is the script:
####################
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 = "chris.yan at xxxx.com"
mailTo = ["chrisyan81 at gmail.com",]
mail = StringIO.StringIO("""Date: Fri, 3 Nov 2006 230:14:39 +0000
From: chris.yan at xxxx.com
To: chrisyan81 at gmail.com
Subject: Tutorate!
Hello, how are you, goodbye.
""")
whenDone = defer.Deferred()
def send(r):
print "message sent:", r
whenDone.addCallbacks(send, log.err)
def done(d):
from twisted.internet import reactor
reactor.callLater(1, reactor.stop)
whenDone.addBoth(done)
sender = smtp.ESMTPSenderFactory(
'chris.yan',
'xxxxxx',
mailFrom,
mailTo,
mail,
whenDone,
requireTransportSecurity=False
)
smtpClientService = internet.TCPClient('smtp.xxxx.com', 25, sender)
smtpClientService.setServiceParent(application)
in fact the script from
http://twistedmatrix.com/pipermail/twisted-python/2006-November/014299.html,and
I didn't modify anything except my own information.Because the smtp
server doesn't support SSL,so I use requireTransportSecurity=False.
here is the output:

but when I use another script which uses smtplib:
SMTP_server='smtp.xxxx.com'
SMTP_user='chris.yan'
SMTP_passwd='xxxxx'
def
send_email(Subject,From,To,Attachment,Body,SMTP_server,SMTP_user,SMTP_passwd):
msg = MIMEMultipart()
msg['Subject'] = Subject
msg['From'] = From
msg['To'] = To
txt = MIMEText(Body,_charset='utf-8')
msg.attach(txt)
filename = Attachment
if not os.path.isfile(filename):
print 'Can not find file %s,please check!' % filename
sys.exit(1)
fp = open(filename,'rb')
ctype,encoding = mimetypes.guess_type(filename)
if ctype is None or encoding is not None:
ctype = 'application/octet-stream'
maintype,subtype = ctype.split('/',1)
m = MIMEBase(maintype,subtype)
m.set_payload(fp.read())
fp.close()
Encoders.encode_base64(m)
m.add_header('Content-disposition','attachment',filename=filename)
msg.attach(m)
s = smtplib.SMTP(SMTP_server)
s.debuglevel = 5
s.ehlo()
s.esmtp_features["auth"] = "LOGIN"
s.login(SMTP_user,SMTP_passwd)
s.sendmail(From,To,msg.as_string())
s.close()
I can get the output:

Done.
some guy said,this script force to use the LOGIN auth,because something
wrong with the server,is it true?I don't know very much about the mail
server,does any one can tell me if I can make my twisted script work?I
really like to implement a twisted one.
BestWishes
Chris
