没有使用Python示例发送电子邮件

Question

我一直在尝试(并且失败)弄清楚如何通过Python发送电子邮件.

试试这里的例子:http: //docs.python.org/library/smtplib.html#smtplib.SMTP

但server = smtplib.SMTP_SSL('smtp.gmail.com', 465)在我没有SSL连接的反弹后添加了这条线.

现在我明白了:

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
>>> 

思考？

server = smtplib.SMTP("smtp.google.com",495)给出了超时错误.只是smtplib.smtp("smtp.google.com",495)给了我"SSLError:[Errno 1] _ssl.c:480:错误:140770FC:SSL例程:SSL23_GET_SERVER_HELLO:未知协议"(见下文).

我正在尝试不同的端口,现在我遇到了一个全新的错误.我只是发布了一些代码,我可能会犯一些菜鸟错误.

"

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()

"

然后我收到此错误消息:"

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')

    SMTP.__init__(self, host, port, local_hostname, timeout)
  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 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

"

请注意,实际上看起来像"server = smtplib.SMTPSSLPORT = 587"实际上是"server = smtplib.SMTP 下划线 SSL 下划线 PORT = 587",这里有某种格式化的事情.

Answer 1

以下代码适用于我:

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()

我正在使用Python 2.5.2.

编辑:根据ΤΖΩΤΖΙΟΥ的建议将端口从25更改为587,并删除第二个ehlo().现在我想知道为什么端口25可以从我的机器完美运行(而端口465 没有).

Answer 2

使用SSL连接到GMail的正确方法是:

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

端口465似乎导致延迟.两个端口都在GMail FAQ中指定.

请注意,使用端口587对于SMTP over SSL更常见,尽管这只是一些简单的信息,但它没有其他实际用途.

这个答案作为社区维基提供,以便被选为"答案".请根据需要改进.

Answer 3

这是一个简单的扔掉解决方案.我想早点粘贴,但在我的椅子上睡着了.

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")

这是我的假设,这个线程上的大多数成功尝试使用其代码的人都不在win32上.;)

Answer 4

问题是由于Python中的错误.尝试使用SMTP_SSL创建连接将失败,并显示"SMTPServerDisconnected:请先运行connect()".

已提交修复程序,因此您可以修补本地副本.请参阅名为"smtplib_72551.diff"的附件.

(注意:SMTP_SSL是添加到Python 2.6/3.0及更高版本的新类.)

Answer 5

也许端口错误？我对smtp.gmail.com使用587，它可以工作。
