python使用SMTP發送qq/sina郵件

python使用qq郵箱（個人郵箱）發送郵件需開啟qq郵箱的SMTP服務

　　在設置中開啟pop3/SMTP服務，返回的密碼就是之后代碼中登錄使用賬戶密碼（在完整代碼中標識了出來）

　　

之后出現如下錯誤

smtplib.SMTPAuthenticationError: (530, 'Error: A secure connection is requiered(such as ssl). More information at http://service.mail.qq.com/cgi-bin/help?id=28')

錯誤說要開ssl發送郵件

在原來的代碼上添加上如下三行代碼即可

smtpObj.ehlo()
smtpObj.starttls()
smtpObj.ehlo()

 

完整代碼如下

import smtplib
from email.mime.text import MIMEText
from email.header import Header

# 第三方 SMTP 服務
mail_host = "smtp.qq.com"  # 設置服務器，qq的SMTP服務host
mail_user = "[e-mail]"  # 用戶名（須修改）
mail_pass = "xxxxxxxxxxxxxxxx"  # 此處為在qq開啟SMTP服務時返回的密碼 （須修改）

sender = '[e-mail]'       # 同用戶名 （須修改）
receivers = ['[e-mail]']  # 接收郵件，可設置為你的QQ郵箱或者其他郵箱

message = MIMEText('...', 'plain', 'utf-8')
message['From'] = Header("第一封python測試郵件", 'utf-8')
message['To'] = Header("測試", 'utf-8')

try:
    subject = 'Python SMTP 郵件測試'
    message['Subject'] = Header(subject, 'utf-8')
    smtpObj = smtplib.SMTP()
    smtpObj.connect(mail_host, 25)  # 25 為 SMTP 端口號
 smtpObj.ehlo() smtpObj.starttls() smtpObj.ehlo()
    smtpObj.login(mail_user, mail_pass)
    smtpObj.sendmail(sender, receivers, message.as_string())
    print "郵件發送成功"
except smtplib.SMTPException :
    print "Error: 無法發送郵件"

 

 

在使用sina郵箱開啟SMPT服務后使用python發送信息卡在了如下錯誤#不是很理解

smtplib.SMTPDataError: (553, 'Envolope sender mismatch with header from..')

成功的例子是

import smtplib
server = "smtp.sina.com"
fromaddr= "[e-mail]" #須修改
toaddr = "[e-mail]"    #須修改
msg = """
to:%s
from:%s
Hello,I am smtp server
""" %(toaddr,fromaddr)
s = smtplib.SMTP(server)
s.set_debuglevel(1)
s.login("[e-mail]","xxx") 　#須修改
s.sendmail(fromaddr,toaddr,msg)

報錯的例子是

import smtplib
from email.mime.text import MIMEText
from email.header import Header
server = "smtp.sina.com"
fromaddr= "[e-mail]"
toaddr = "[e-mail]"

message = MIMEText('...', 'plain', 'utf-8')
message['From'] = Header(fromaddr, 'utf-8')
message['To'] = Header("toaddr", 'utf-8')
subject = 'Python SMTP 郵件測試'
message['Subject'] = Header(subject, 'utf-8')

s = smtplib.SMTP(server)
s.set_debuglevel(1)
s.login("[e-mail]","xxx")
s.sendmail(fromaddr,toaddr,message)
