How to Configure QQ Email SMTP and Send Emails with Python

1. Understand QQ Email SMTP

QQ email POP3 and SMTP server addresses are as follows:

Email

POP3 Server (Port 995)

SMTP Server (Port 465 or 587)

qq.com

pop.qq.com

smtp.exmail.qq.com

The SMTP server requires authentication.

2. Enable QQ Email SMTP Service

How to turn on POP3/SMTP/IMAP?

To protect user security, QQ email disables POP3/SMTP/IMAP by default; you need to enable them when required. First, log in to the mailbox and go to Settings → Account.

Then, in the Account settings, locate the toggle items and enable them as shown below:

Finally, save the settings to activate the corresponding services.

3. Code

import smtplib
from email.mime.text import MIMEText
from email.utils import formataddr

my_sender = '[email protected]'     # sender email address
my_pass = 'xxxxxx'               # sender email password (SMTP token)
my_user = '[email protected]'        # recipient email address (sending to self)

def mail():
    ret = True
    try:
        msg = MIMEText('填写邮件内容', 'plain', 'utf-8')
        msg['From'] = formataddr(["发件人昵称", my_sender])   # sender nickname and address
        msg['To'] = formataddr(["收件人昵称", my_user])      # recipient nickname and address
        msg['Subject'] = "邮件主题-测试"                     # email subject

        server = smtplib.SMTP_SSL("smtp.exmail.qq.com", 465)  # SMTP server and port
        server.login(my_sender, my_pass)                     # authenticate
        server.sendmail(my_sender, [my_user], msg.as_string()) # send email
        server.quit()                                         # close connection
    except Exception:
        ret = False
    return ret

ret = mail()
if ret:
    print("邮件发送成功")
else:
    print("邮件发送失败")

Note: If the recipient address is incorrect, the script may still print “邮件发送成功”, but QQ will return a bounce message indicating delivery failure.
