a connection is required before login and sendemail.
登录和发送电子邮件之前需要连接。
server = smtplib.SMTP('smtp.example.com', 25)
server.connect("smtp.example.com",465)
server.ehlo()
server.starttls()
server.ehlo()
server.login(fromaddr, "password")
text = msg.as_string()
server.sendmail(fromaddr, toaddr, text)
server.quit()

It is probably just the server I was using, but was getting the same error as the OP even after implementing the accepted solution. Turned out the server did not want a login, so after deleting the line server.login(fromaddr, "password"), the error went away and it worked.
它可能只是我正在使用的服务器，但即使在实施了公认的解决方案后，也遇到了与 OP 相同的错误。原来服务器不想登录，所以删除该行后server.login(fromaddr, "password")，错误消失了，它起作用了。

import smtplib
s = smtplib.SMTP('smtplib.gmail.com',587)
s.ehlo()
s.starttls()
s.login('frmaddr','password')
try:
s.sendmail('fromaddr','toaddr','message')
except:
print (failed)

There is no need to call smtp.connect()and smtp.ehlo(), because they are called automatically by SMTP()and smtp.starttls(). The issue is solved simply setting port to 587instead of 28.
不需要调用smtp.connect()and smtp.ehlo()，因为它们会被SMTP()and自动调用smtp.starttls()。只需将端口设置为587而不是28.
For client use, if you don't have any special requirements for your security policy, it is highly recommended that you use the create_default_context()function to create your SSL context. It will load the system's trusted CA certificates, enable certificate validation and hostname checking, and try to choose reasonably secure protocol and cipher settings.
对于客户端使用，如果您对您的安全策略没有任何特殊要求，强烈建议您使用该create_default_context()功能来创建您的 SSL 上下文。它将加载系统的可信 CA 证书，启用证书验证和主机名检查，并尝试选择合理安全的协议和密码设置。
In general, you will want to use the emailpackage's features to construct an email message, which you can then send via send_message().
通常，您会希望使用email包的功能来构建电子邮件，然后您可以通过send_message().
import smtplib, ssl
from email.message import EmailMessage
msg = EmailMessage()
msg.set_content("The body of the email is here")
msg["Subject"] = "An Email Alert"
msg["From"] = "[email protected]"
msg["To"] = "[email protected]"
context=ssl.create_default_context()
with smtplib.SMTP("smtp.example.com", port=587) as smtp:
smtp.starttls(context=context)
smtp.login(msg["From"], "p@55w0rd")
smtp.send_message(msg)

The first tap is enable your gmail account to send emails by another applications, allow in this section:
第一次点击是启用您的 Gmail 帐户以通过其他应用程序发送电子邮件，在此部分中允许：
https://myaccount.google.com/lesssecureapps
https://myaccount.google.com/lesssecureapps
Then, you should can to send an email
然后，您应该可以发送电子邮件
import json
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
import smtplib
msg = MIMEMultipart()
message = "This is an email"
password = "yourpasswordemailsender"
msg['From'] = "[email protected]"
msg['To'] = "[email protected]"
msg['Subject'] = "Title of email"
msg.attach(MIMEText(message, 'plain'))
server = smtplib.SMTP('smtp.gmail.com: 587')
server.starttls()
server.login(msg['From'], password)
server.sendmail(msg['From'], msg['To'], msg.as_string())
server.quit()

you need to 'starttls' before login.
您需要在登录前“starttls”。
