Get e-mail addresses from Gmail messages received
I have a Google Apps Gmail account and I would like to extract all email adresses in the from and to (and cc, bcc and reply-to if possible) headers of every message.
How can I do this?
I've found a site (https://gmailextract.com/) that promises to do exactly what I need, but I don't think I can trust it with my password.
