Failing to send email with the Python example

问题

I've been trying (and failing) to figure out how to send email via Python.

Trying the example from here: http://docs.python.org/library/smtplib.html#smtplib.SMTP

but added the line server = smtplib.SMTP_SSL('smtp.gmail.com', 465) after I got a bounceback about not having an SSL connection.

Now I'm getting this:

Traceback (most recent call last):
  File "C:/Python26/08_emailconnects/12_29_EmailSendExample_NotWorkingYet.py", line 37, in <module>
    server = smtplib.SMTP('smtp.gmail.com', 65)
  File "C:\Python26\lib\smtplib.py", line 239, in __init__
    (code, msg) = self.connect(host, port)
  File "C:\Python26\lib\smtplib.py", line 295, in connect
    self.sock = self._get_socket(host, port, self.timeout)
  File "C:\Python26\lib\smtplib.py", line 273, in _get_socket
    return socket.create_connection((port, host), timeout)
  File "C:\Python26\lib\socket.py", line 512, in create_connection
    raise error, msg
error: [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond
>>>

Thoughts?

server = smtplib.SMTP("smtp.google.com", 495) gives me a timeout error. just smtplib.smtp("smtp.google.com", 495) gives me "SSLError: [Errno 1] _ssl.c:480: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol" (see below).

I'm trying different ports and now I'm getting a completely new error. I'll just post the whole bit of code, I'm probably making some rookie mistake.

import smtplib

mailuser = 'MYEMAIL@gmail.com'

mailpasswd = 'MYPASSWORD'

fromaddr = 'MYEMAIL@gmail.com'

toaddrs = 'MYEMAIL2@gmail.com'

msg = 'Hooooorah!'

print msg

server = smtplib.SMTP_SSL('smtp.google.com')

server = smtplib.SMTP_SSL_PORT=587

server.user(mailuser)

server.pass_(mailpasswd)

server.set_debuglevel(1)

server.sendmail(fromaddr, toaddrs, msg)

server.quit()

and then I get this error message: "

Traceback (most recent call last):
  File "C:/Python26/08_emailconnects/12_29_eMAILSendtryin_stripped.py", line 16, in <module>
    server = smtplib.SMTP_SSL('smtp.google.com')

  File "C:\Python26\lib\smtplib.py", line 295, in connect
    self.sock = self._get_socket(host, port, self.timeout)
  File "C:\Python26\lib\smtplib.py", line 755, in _get_socket
    self.sock = ssl.wrap_socket(self.sock, self.keyfile, self.certfile)
  File "C:\Python26\lib\ssl.py", line 350, in wrap_socket
    suppress_ragged_eofs=suppress_ragged_eofs)
  File "C:\Python26\lib\ssl.py", line 118, in __init__
    self.do_handshake()
  File "C:\Python26\lib\ssl.py", line 293, in do_handshake
    self._sslobj.do_handshake()
SSLError: [Errno 1] _ssl.c:480: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

note that actually the which looks like "server = smtplib.SMTPSSLPORT=587" is actually "server = smtplib.SMTP underscore SSL underscore PORT=587", there's some sort of formatting thing going on here.

The following code works for me:

import smtplib

FROMADDR = "my.real.address@gmail.com"
LOGIN    = FROMADDR
PASSWORD = "my.real.password"
TOADDRS  = ["my.real.address@gmail.com"]
SUBJECT  = "Test"

msg = ("From: %s\r\nTo: %s\r\nSubject: %s\r\n\r\n"
       % (FROMADDR, ", ".join(TOADDRS), SUBJECT) )
msg += "some text\r\n"

server = smtplib.SMTP('smtp.gmail.com', 587)
server.set_debuglevel(1)
server.ehlo()
server.starttls()
server.login(LOGIN, PASSWORD)
server.sendmail(FROMADDR, TOADDRS, msg)
server.quit()

I'm using Python 2.5.2.

Edit: changed port from 25 to 587 as suggested by ΤΖΩΤΖΙΟΥ, and dropped the second ehlo(). Now I would love to know why port 25 works perfectly from my machine (and port 465 does not).

回答2:

The correct way to connect to GMail using SSL is:

server = smtplib.SMTP('smtp.gmail.com', 587)

Port 465 seems to cause delays. Both ports are specified in a GMail FAQ.

Note that use of port 587 is more common for SMTP over SSL, although this is just trivial information, it has no other practical use.

回答3:

The problem is due to a bug in Python. Trying to create a connection with SMTP_SSL will fail with "SMTPServerDisconnected: please run connect() first."

A fix has been committed, so you can patch your local copy. See the attachment named "smtplib_72551.diff".

(Note: SMTP_SSL is a new class added to Python 2.6/3.0 and later.)

Here's a simple throw away solution. Meant to paste this earlier, but fell asleep at my chair.


import smtplib
import email
import os

username = "user@gmail.com"
passwd = "password"

def mail(to, subject, text, attach):
   msg = MIMEMultipart()

   msg['From'] = username
   msg['To'] = to
   msg['Subject'] = subject

   msg.attach(MIMEText(text)) 

   part = MIMEBase('application', 'octet-stream')
   part.set_payload(open(attach, 'rb').read())
   Encoders.encode_base64(part)
   part.add_header('Content-Disposition',
           'attachment; filename="%s"' % os.path.basename(attach))
   msg.attach(part)

   server = smtplib.SMTP("smtp.gmail.com", 495)
   server.ehlo()
   server.starttls()
   server.ehlo()
   server.login(username, passwd)
   server.sendmail(username, to, msg.as_string())
   server.close()

mail("you", "hi", "hi", "webcam.jpg")

It's my assumption that most people on this thread that have had successful attempts with their code aren't on win32. ;)

*edit: See http://docs.python.org/library/email-examples.html for some good "official" examples.

Okay, found out that this line of code does the trick!

server = smtplib.SMTP('smtp.gmail.com', 587 )

Turned out to be GMAIL didn't support SSL on port 25 (and port 465 caused a hang for some reason).

Thanks guys!

回答6:

You should check your port, I'm not sure that google's SMTP port is 65, that would explain the timeout.

Modify your sources as such:

smtplib.SMTP_SSL('smtp.google.com', 465)

If, however, you are certain that it ought to work and it doesn't, it appears that there are some problems with smtplib.SMTP_SSL, and there's an available patch for it here.

回答7:

Incorrect port maybe? I'm using 587 for smtp.gmail.com and it works.

回答8:

from smtplib import SMTP_SSL as SMTP
from email.mime.text import MIMEText

HOST = 'smtp.gmail.com'
PORT = 465

USERNAME = 'oltjano13@gmail.com'
PASSWORD = ''

SENDER = 'oltjano13@gmail.com'
RECIPIENT = 'oltjano13@gmail.com'

text_subtype = 'plain'

with open('textfile', 'rb') as f:
    msg = MIMEText(f.read(), text_subtype)


msg['Subject'] = 'Python Script'
msg['From'] = SENDER
msg['To'] = RECIPIENT

try:
    connection = SMTP(HOST, PORT)
    connection.login(USERNAME, PASSWORD)
    connection.sendmail(SENDER, RECIPIENT, msg.as_string())
except Exception, e:
    print(e)

The above code works fine for me. As you can see the PORT = 465 is being used in this example since I am using SSL. If you plan to use the port 587 then TLS is required.

回答9:

import smtplib

content = 'example email stuff here'

mail = smtplib.SMTP('smtp.gmail.com', 587)

mail.ehlo()

mail.starttls()

mail.login('email@gmail.com','password')

mail.sendmail('email@gmail.com', 'email@yahoo.com', content)

mail.close()
