Python uses SMTP to send qq or sina emails, pythonsmtp

Python needs to enable the SMTP service for sending mails via QQ mail (Personal mailbox)

Enable the pop3/SMTP service in settings. The returned password is the account password used to log on to the system in the Code (identified in the complete code)

The following error occurs:

Copy codeThe Code is as follows: 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 ')

The error message is that you want to enable ssl to send an email.

Add the following three lines of code to the original code:

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

The complete code is as follows:

Import smtplibfrom email. mime. text import MIMETextfrom email. header import Header # third-party SMTP service mail_host = "smtp.qq.com" # Set the server, qq SMTP service hostmail_user = "xxx@qq.com" # User Name (must be modified) mail_pass = "xxxxxxxxxxxxxxxx" # Here is the password returned when the SMTP service is enabled on qq (must be modified) sender = 'xxx @ qq.com '# Same user name (must be modified) receivers = ['xxx @ qq.com '] # To receive emails, you can set it to your QQ mailbox or other email message = MIMEText ('... ', 'plain', 'utf-8') message ['from'] = Header ("the first python test email", 'utf-8 ') message ['to'] = Header ("test", 'utf-8') try: subject = 'python SMTP mail test 'message ['subobject'] = Header (Subject, 'utf-8') smtpObj = smtplib. SMTP () smtpObj. connect (mail_host, 25) #25 is the SMTP port number smtpObj. ehlo () smtpObj. starttls () smtpObj. ehlo () smtpObj. login (mail_user, mail_pass) smtpObj. sendmail (sender, receivers, message. as_string () print "email sent successfully" cannot smtplib. SMTPException: print "Error: unable to send mail"

The following error occurs when you use python to send information after you enable the SMPT service in sina mail. # Not very understandable.

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

The success example is:

Import smtplibserver = "smtp.sina.com" fromaddr = "xxx@sina.com" # toaddr = "xxx@qq.com" # Must be modified msg = "to: % sfrom: % sHello, I am smtp server "% (toaddr, fromaddr) s = smtplib. SMTP (server) s. set_debuglevel (1) s. login ("xxx@sina.com", "xxx") # s. sendmail (fromaddr, toaddr, msg)

An example of an error is:

Import smtplibfrom email. mime. text import MIMETextfrom email. header import Headerserver = "smtp.sina.com" fromaddr = "xxx@sina.com" toaddr = "xxx@qq.com" message = MIMEText ('... ', 'plain', 'utf-8') message ['from'] = Header (fromaddr, 'utf-8 ') message ['to'] = Header ("toaddr", 'utf-8') subject = 'python SMTP mail test 'message ['subobject'] = Header (Subject, 'utf-8') s = smtplib. SMTP (server) s. set_debuglevel (1) s. login ("xxx@sina.com", "xxx") s. sendmail (fromaddr, toaddr, message)
