Python使用Gmail发邮件

有时候需要备份些东西到邮箱，能够让脚本定时自动运行当然是最好！ 抽时间用python写了这么个脚本，使用python-libgmail库 ( sudo apt-get install python-libgmail )

 msend -t  [email?protected] -s "求助，图形界面进不了，哈哈”

 msend -t [email?protected] -f readme.txt
    msend -t [email?protected] *.txt

 msend -t [email?protected] -z ./pics/

    Usage:
        msend -t [email?protected] -s title
        msend -t [email?protected] {-s title | -f file | -z file}

    Full command:
        msend [email?protected] --subject=title [--msg=body] [--files="file1;dir2"] [--zip="file1;dir2"]

    Example: ( edit ~/.msend for default sender account )
        msend -t [email?protected] -s "just a test"
        msend -t [email?protected] -s "send all pic" -f ./mypics/
        msend -t [email?protected] -s "send files as zip" -z ./mytext/
        msend -t [email?protected] -s "send both" -f mytext -z mytext
