Python: How to Send an E-mail

Python: Eメールの送信

 

何度も車輪の再発明を繰り返しているが、今のところちょっとしたスクリプトにおいては
以下の内容で落ち着いている。

同じ階層に conf ファイルを置く。

mail_sender.conf

[system] smtp-server: {{ smtp_server }} smtp-port: {{ smtp_port }}   [awesome-project] from-address: {{ from_address }} to-address-list: {{ to_address_list }}

{{ }} の部分は適宜書き換え。to_address_list はカンマ区切りで複数指定可能。
