嘗試使用python smtplib發送電子郵件時出錯

Question

import smtplib

host = 'smtp.gmail.com'
port = 587
username = 'rajinirajadev@gmail.com'
password = '*************'
from_email = username
to_list = ['rajiniraja00@gmail.com']

email_conn = smtplib.SMTP(host,port)
email_conn.ehlo()
email_conn.starttls()
email_conn.login(username, password)
email_conn.sendmail(from_email, to_list, 'that is send via smtplib')
email_conn.quit()

這是我得到的錯誤。 我關閉了兩步驗證，然后打開了允許在Gmail上使用安全的應用程序。

Answer 1

當我使用我的gmail帳戶發送電子郵件時，我也遇到了同樣的問題。 即通過主機='smtp.gmail.com'

但是，當我使用我的Outlook帳戶（即通過host ='smtp.outlook.com'）時，此問題已解決，並且收到的消息為“（（235，b'2.7.0身份驗證成功'）”

結論-Gmail垃圾郵件安全性被阻止，因為它認為腳本是某些不受信任的來源，並向我各自的帳戶發送了一封郵件，該腳本已阻止登錄免除
