學習如何利用python send Email (SMTP setting/ message/)

• SMTP : Single Mail Transfer Protocal
• Python 已內建 smtplib module
  • daemon (background process) wait for request /wake up
• 大型公司會有 smtp server support this function (ex smtp.google.com)

Sending E-mail

1. Import smtplib
2. smtplib.SMTP(”Domain_name”, port number)
   1. 設定smtp server
   2. port: 587 → 利用RSA 演算法加密

SMTP method:

1. ehlo(): Hello method 確立連線
2. starttls(): TLS (Transport Layer Security)
3. Login() : add username/password
