Slack から メールを送れるようにしてみた ～その１～ ref: http://qiita.com/sasaco/items/1bcb0a6f33ef3ca88394

Code

var json = JSON.parse(inputData.data);
var to_mail = (json.to.match(/([\w._-]+@[\w._-]+\.[\w._-]+)/gi) || [])[0];

output = [
  {
    to : to_mail,
    cc: json.cc,
    bcc: json.bcc,
    subject: json.subject,
    body: json.body,
    attachment: json.attachment   
  }
];

    "cc": null,
