python 으로 간단하게 email 전송하기

참고로 email.py 라는 이름은 되도록 피하기 바란다.(참고 : Unable to import Python's email module at all - Stack Overflow)

gmail 이용시

• ref 3: How to Send Emails with Gmail using Python

기본적으로 google 이 unsecured app 에 대한 접근을 막고 있다. 그래서 이것을 풀어줘야 한다. (SMTP 로 login 하는 것이 unsecure 하긴 하니..) 아래 경로로 가면 된다.

• https://www.google.com/settings/security/lesssecureapps

개인적으로는 이정도까지 하면 gmail 을 사용할 수 있었다.

ref. 3 에서는 그밖에 captcha 등을 꺼야하는 등의 이야기도 있으니 참고하자.
