530错误 - Google SMTP服务器需要身份验证

Question

我无法使用Mail to：SMTP命令在此python套接字程序中工作。我总是...

530-5.5.1 Authentication Required 

...你可以看到，我不提供ca_certs和cert_reqs参数。我似乎无法找到在Python for Windows中使用证书进行编程的任何好例子。

from socket import * 
import ssl, pprint 

msg = "\r\n I love computer networks!" 
endmsg = "\r\n.\r\n" 

# Choose a mail server (e.g. Google mail server) and call it mailserver 
mailserver = "smtp.gmail.com" 
port = 465 

# Create socket called clientSocket and establish a TCP connection with mailserver 
clientSocket = socket(AF_INET, SOCK_STREAM) 
ssl_clientSocket = ssl.wrap_socket(clientSocket) 
            #ca_certs="C:\Users\wgimson\Downloads\root", 
            #cert_reqs=ssl.CERT_REQUIRED) 
ssl_clientSocket.connect((mailserver, port)) 

# DEBUG 
print repr(ssl_clientSocket.getpeername()) 
print ssl_clientSocket.cipher() 
print pprint.pformat(ssl_clientSocket.getpeercert()) 
# DEBUG 


recv = ssl_clientSocket.read(1024) 
print 
print recv 


# If the first three numbers of what we receive from the SMTP server are not 
# '220', we have a problem 
if recv[:3] != '220': 
    print '220 reply not received from server.' 
else: 
    print "220 is good" 

# Send HELO command and print server response. 
heloCommand = 'HELO Alice\r\n' 
ssl_clientSocket.write(heloCommand) 
recv1 = ssl_clientSocket.recv(1024) 
print recv1 


# If the first three numbers of the response from the server are not 
# '250', we have a problem 
if recv1[:3] != '250': 
    print '250 reply not received from server.' 
else: 
    print "250 is good" 


# Send MAIL FROM command and print server response. 
mailFromCommand = 'MAIL From: wgimson@gmail.com\r\n' 
ssl_clientSocket.send(mailFromCommand) 
recv2 = ssl_clientSocket.recv(1024) 
print recv2 

# If the first three numbers of the response from the server are not 
# '250', we have a problem 
if recv2[:3] != '250': 
    print '250 reply not received from server.' 
else: 
    print "250 means still good"

这适用于Google邮件。

def send_mail(recipient, subject, message, contenttype='plain'): 
    EMAIL_HOST = 'smtp.gmail.com' 
    EMAIL_PORT = 587 
    EMAIL_HOST_USER = 'some_account@gmail.com' 
    EMAIL_HOST_PASSWORD = 'some_password' 

    mime_msg = email.mime.text.MIMEText(message, contenttype, _charset="UTF-8") 
    mime_msg['Subject'] = subject 
    mime_msg['From'] = EMAIL_HOST_USER 
    mime_msg['To'] = recipient 

    smtpserver = smtplib.SMTP(EMAIL_HOST, EMAIL_PORT) 
    smtpserver.ehlo() 
    smtpserver.starttls() 
    smtpserver.login(EMAIL_HOST_USER, EMAIL_HOST_PASSWORD) 
    smtpserver.sendmail(EMAIL_HOST_USER, recipient, mime_msg.as_string()) 
    smtpserver.close()
