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()
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”。
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())
def send_email(user, pwd, recipient, subject, body):
import smtplib
FROM = user
TO = recipient if isinstance(recipient, list) else [recipient]
SUBJECT = subject
TEXT = body
# Prepare actual message
message = """From: %s\nTo: %s\nSubject: %s\n\n%s
""" % (FROM, ", ".join(TO), SUBJECT, TEXT)
try:
server = smtplib.SMTP("smtp.gmail.com", 587)
server.ehlo()
server.starttls()
server.login(user, pwd)
server.sendmail(FROM, TO, message)
server.close()
print 'successfully sent the mail'
except:
print "failed to send mail"
如果你想使用端口465,你必须创建一个SMTP_SSL对象:
# SMTP_SSL Example
server_ssl = smtplib.SMTP_SSL("smtp.gmail.com", 465)
server_ssl.ehlo() # optional, called by login()
server_ssl.login(gmail_user, gmail_pwd)
# ssl server doesn't support or need tls, so don't call server_ssl.starttls()
server_ssl.sendmail(FROM, TO, message)
#server_ssl.quit()
server_ssl.close()
print 'successfully sent the mail'
你同意OOP吗?
#!/usr/bin/env python
import smtplib
class Gmail(object):
def __init__(self, email, password):
self.email = email
self.password = password
self.server = 'smtp.gmail.com'
self.port = 587
session = smtplib.SMTP(self.server, self.port)
session.ehlo()
session.starttls()
session.ehlo
session.login(self.email, self.password)
self.session = session
def send_message(self, subject, body):
''' This must be removed '''
headers = [
"From: " + self.email,
"Subject: " + subject,
"To: " + self.email,
"MIME-Version: 1.0",
"Content-Type: text/html"]
headers = "\r\n".join(headers)
self.session.sendmail(
self.email,
self.email,
headers + "\r\n\r\n" + body)
gm = Gmail('Your Email', 'Password')
gm.send_message('Subject', 'Message')
我遇到过类似的问题,并无意中发现了这个问题。我得到一个SMTP身份验证错误,但我的用户名/ pass是正确的。下面是解决问题的方法。我读到:
https://support.google.com/accounts/answer/6010255
简而言之,谷歌不允许您通过smtplib登录,因为它已经标记了这种登录为“不太安全”,所以你要做的是去这个链接,而你登录到你的谷歌帐户,并允许访问:
https://www.google.com/settings/security/lesssecureapps
一旦设置好了(见下面的截图),它就可以工作了。
登录现在工作:
smtpserver = smtplib.SMTP("smtp.gmail.com", 587)
smtpserver.ehlo()
smtpserver.starttls()
smtpserver.ehlo()
smtpserver.login('me@gmail.com', 'me_pass')
更改后的回复:
(235, '2.7.0 Accepted')
响应之前:
smtplib.SMTPAuthenticationError: (535, '5.7.8 Username and Password not accepted. Learn more at\n5.7.8 http://support.google.com/mail/bin/answer.py?answer=14257 g66sm2224117qgf.37 - gsmtp')
还是不行?如果您仍然得到SMTPAuthenticationError,但现在代码是534,这是因为位置未知。点击这个链接:
https://accounts.google.com/DisplayUnlockCaptcha
点击继续,这应该给你10分钟的时间来注册你的新应用。所以现在继续进行另一次登录尝试,它应该可以工作。
更新:这似乎不能马上工作,你可能会卡在smptlib中得到这个错误:
235 == 'Authentication successful'
503 == 'Error: already authenticated'
该消息说使用浏览器登录:
SMTPAuthenticationError: (534, '5.7.9 Please log in with your web browser and then try again. Learn more at\n5.7.9 https://support.google.com/mail/bin/answer.py?answer=78754 qo11sm4014232igb.17 - gsmtp')
启用“lesssecureapps”后,去喝杯咖啡,回来后再次尝试“DisplayUnlockCaptcha”链接。从用户体验来看,更改可能需要一个小时才能生效。然后再次尝试登录过程。
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。
来自@David的很棒的回答,这里是Python 3没有通用的try-除了:
def send_email(user, password, recipient, subject, body):
gmail_user = user
gmail_pwd = password
FROM = user
TO = recipient if type(recipient) is list else [recipient]
SUBJECT = subject
TEXT = body
# Prepare actual message
message = """From: %s\nTo: %s\nSubject: %s\n\n%s
""" % (FROM, ", ".join(TO), SUBJECT, TEXT)
server = smtplib.SMTP("smtp.gmail.com", 587)
server.ehlo()
server.starttls()
server.login(gmail_user, gmail_pwd)
server.sendmail(FROM, TO, message)
server.close()
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:

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。
下面是一个Gmail API的例子。虽然比较复杂,但这是我发现在2019年唯一有效的方法。这个例子是从以下例子中获取并修改的:
https://developers.google.com/gmail/api/guides/sending
你需要通过谷歌的网站创建一个API接口的项目。接下来,你需要为你的应用程序启用GMAIL API。创建凭证,然后下载这些凭证,保存为credentials.json。

在您的gmail帐户上启用不太安全的应用程序,并使用(Python>=3.6):
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
gmailUser = 'XXXXX@gmail.com'
gmailPassword = 'XXXXX'
recipient = 'XXXXX@gmail.com'
message = f"""
Type your message here...
"""
msg = MIMEMultipart()
msg['From'] = f'"Your Name" <{gmailUser}>'
msg['To'] = recipient
msg['Subject'] = "Subject here..."
msg.attach(MIMEText(message))
try:
mailServer = smtplib.SMTP('smtp.gmail.com', 587)
mailServer.ehlo()
mailServer.starttls()
mailServer.ehlo()
mailServer.login(gmailUser, gmailPassword)
mailServer.sendmail(gmailUser, recipient, msg.as_string())
mailServer.close()
print ('Email sent!')
except:
print ('Something went wrong...')
意识到用Python发送电子邮件有多痛苦,所以我为它做了一个广泛的库。它也有Gmail预配置(所以你不需要记住Gmail的主机和端口):
from redmail import gmail
gmail.user_name = "you@gmail.com"
gmail.password = "<YOUR APPLICATION PASSWORD>"
# Send an email
gmail.send(
subject="An example email",
receivers=["recipient@example.com"],
text="Hi, this is text body.",
html="<h1>Hi, this is HTML body.</h1>"
)
当然你需要配置你的Gmail账号(别担心,很简单):
设置两步验证(如果尚未设置)
创建应用程序密码
将应用程序密码设置为gmail对象,完成!
红色邮件实际上是相当广泛的(包括附件,嵌入图像,发送与抄送和密件,模板与Jinja等),应该是所有你需要从电子邮件发件人。它也经过了良好的测试和文档记录。我希望它对你有用。
如何安装:
pip install redmail
文档:https://red-mail.readthedocs.io/en/latest/
源代码:https://github.com/Miksus/red-mail
注意,Gmail不允许更改发送方。发件人地址永远是你。
2022年12月更新:
您需要使用应用程序密码,以允许您的应用程序访问您的谷歌帐户。
使用应用程序密码登录:
应用程序密码是一个16位数的密码,给一个不太安全的应用程序或
设备权限以访问您的谷歌帐户。应用程序密码
仅用于已开启两步验证的帐户。
此外,谷歌自2022年5月30日起不允许您的应用程序使用用户名(电子邮件地址)和密码访问您的谷歌帐户。所以现在,你需要用户名(电子邮件地址)和应用程序密码来访问你的谷歌帐户。
不太安全的应用和你的谷歌账户:
为了保证您的账户安全,从2022年5月30日起,谷歌号
long支持使用第三方应用程序或设备来询问您
仅使用您的用户名和登录您的谷歌帐户
密码。
如何生成应用程序密码:
首先,从9个点中点击Account:
然后,点击安全中的应用程序密码。*不要忘记在生成应用程序密码之前打开两步验证,否则您无法生成应用程序密码:
然后,点击其他(自定义名称):
然后,输入你的应用程序名称,然后点击GENERATE:
最后,你可以生成应用程序密码xylnudjdiwpojwzm:
所以,你的代码与上面的应用程序密码如下所示:
import smtplib
fromaddr = 'user_me@gmail.com'
toaddrs = 'user_you@gmail.com'
msg = 'Why,Oh why!'
username = 'user_me@gmail.com'
password = 'xylnudjdiwpojwzm' # Here
server = smtplib.SMTP('smtp.gmail.com:587')
server.starttls()
server.login(username,password)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()
另外,在Django中,带有上述应用程序密码的settings.py如下所示:
# "settings.py"
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = 'myaccount@gmail.com'
EMAIL_HOST_PASSWORD = 'xylnudjdiwpojwzm' # Here
