setup.md

Installation

1. Create a new Google Drive Script [Howto].
2. Paste in contents of code.gs and execute function setup().
3. Modify contents of gmailfilter.xml to match your domain.
4. Go to email settings and import gmailfilter.xml.
5. Setup time based trigger (I recommend at the very least every 10 minutes. I have mine set to 1 minute.)
6. That's it! (Monitor inbox for success)

usage.md

End user usage:

• Send an email to [email protected]
• If using provided Gmail Filter follow format for proper subject: Allow 127.0.0.1 192.168.0.1 (Replace with IP's that need unblocking.)
• Email body is not needed.
