A tutorial on Python sending messages with the contents of an entire folder as attachments

This article mainly describes a tutorial that Python sends messages that are attached to the contents of the entire folder. Ordinary we are in the carrier free mailbox send attachments usually can only send files and cannot send folders, and the script can be implemented to send the folder (their own hands-on programming powerful: D), the need for friends can refer to the

Because I often need to back up the contents of the folder in the mail, each open mail, upload files, send, too troublesome, in fact, each send the files are placed in a fixed, but the message header is different, so with Python for their own write a file to the mailbox of a gadget, in any directory to execute the script, and specify the message headers, the files under the specified folder are sent to the mailbox to be backed up.

Installation:

Configure the recipient, sender, SMTP address, username, password, and the path where you want to send the file.

Save the file as Send_files and save it under/usr/bin.

Then set the file permissions to executable:

?

1	$ chmod +x Send_files

Usage:

?

1	$ send_files ' mail title '

Also with the progress bar Oh ~ ~
