mail.py 配置檔案如下

##定義QQ郵箱的賬號和密碼，你需要修改成你自己的賬號和密碼（請不要把真實的使用者名稱和密碼放到網上公開，否則你會死的很慘）
sendqqmail('[email protected]','aaaaaaaaaa','[email protected]',to,subject,content)

if name == "main":
main()

#####指令碼使用說明######
#1. 首先定義好指令碼中的郵箱賬號和密碼
#2. 指令碼執行命令為：python mail.py 目標郵箱 "郵件主題" "郵件內容"

難點在於mail.sh中 計時與計數的邏輯關係。
