我试图使用python发送电子邮件(Gmail),但我得到以下错误。

Traceback (most recent call last):  
File "emailSend.py", line 14, in <module>  
server.login(username,password)  
File "/usr/lib/python2.5/smtplib.py", line 554, in login  
raise SMTPException("SMTP AUTH extension not supported by server.")  
smtplib.SMTPException: SMTP AUTH extension not supported by server.

Python脚本如下所示。

import smtplib

fromaddr = 'user_me@gmail.com'
toaddrs  = 'user_you@gmail.com'
msg = 'Why,Oh why!'
username = 'user_me@gmail.com'
password = 'pwd'
server = smtplib.SMTP('smtp.gmail.com:587')
server.starttls()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()

当前回答

你可以在这里找到它:http://jayrambhia.com/blog/send-emails-using-python

smtp_host = 'smtp.gmail.com'
smtp_port = 587
server = smtplib.SMTP()
server.connect(smtp_host,smtp_port)
server.ehlo()
server.starttls()
server.login(user,passw)
fromaddr = raw_input('Send mail by the name of: ')
tolist = raw_input('To: ').split()
sub = raw_input('Subject: ')

msg = email.MIMEMultipart.MIMEMultipart()
msg['From'] = fromaddr
msg['To'] = email.Utils.COMMASPACE.join(tolist)
msg['Subject'] = sub  
msg.attach(MIMEText(raw_input('Body: ')))
msg.attach(MIMEText('\nsent via python', 'plain'))
server.sendmail(user,tolist,msg.as_string())

其他回答

不直接相关,但仍然值得指出的是,我的包试图使发送gmail消息非常快速和轻松。它还试图维护一个错误列表,并试图立即指出解决方案。

它只需要下面的代码来完成你所写的:

import yagmail
yag = yagmail.SMTP('user_me@gmail.com')
yag.send('user_you@gmail.com', 'Why,Oh why!')

或者一句话:

yagmail.SMTP('user_me@gmail.com').send('user_you@gmail.com', 'Why,Oh why!')

关于包/安装,请查看git或pip,可用于Python 2和3。

你需要在直接运行到STARTTLS之前说EHLO:

server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo()
server.starttls()

此外,您应该真正创建From:、To:和Subject:消息头,用空行与消息体分隔,并使用CRLF作为EOL标记。

E.g.

msg = "\r\n".join([
  "From: user_me@gmail.com",
  "To: user_you@gmail.com",
  "Subject: Just a message",
  "",
  "Why, oh why"
  ])

注意:

为了做到这一点,你需要在gmail帐户配置中启用“允许不太安全的应用程序”选项。否则,当gmail检测到一个非谷歌应用程序试图登录你的帐户时,你会得到一个“关键安全警报”。

这是

创建Gmail APP密码!

创建之后,创建一个名为sendgmail.py的文件

然后添加以下代码:

try:
    server = smtplib.SMTP_SSL('smtp.gmail.com', 465)
    server.ehlo()
    server.login(gmail_user, gmail_app_password)
    server.sendmail(sent_from, sent_to, email_text)
    server.close()

    print('Email sent!')
except Exception as exception:
    print("Error: %s!\n\n" % exception)

所以,如果你成功了,你会看到这样的图像:

我通过给自己和自己发送电子邮件进行测试。

注意:我在我的帐户上启用了两步验证。应用程序密码与此工作!(对于gmail SMTP设置,您必须访问https://support.google.com/accounts/answer/185833?hl=en并遵循以下步骤) 此设置对于启用了两步验证的帐户不可用。这样的帐户需要特定于应用程序的密码来访问不太安全的应用程序。

澄清

导航到https://myaccount.google.com/apppasswords,并创建一个APP密码如上所述。

import smtplib
server = smtplib.SMTP('smtp.gmail.com', 587)
server.ehlo()
server.starttls()
server.login("fromaddress", "password")
msg = "HI!"
server.sendmail("fromaddress", "receiveraddress", msg)
server.quit()

似乎是老smtplib的问题。在python2.7中,一切正常。

更新:是的,server.ehlo()也可以帮助。
