At one point it was possible to use scripts like libgmail and gmail.py (can't post more than one hyperlink) to export mail from Gmail accounts. Both of those seem to not work anymore — I can't even log in with them. I assume it's because there's been some changes in Gmail. Is there still any way to do this?
回答1:
Gmail supports IMAP and POP, which are common protocols for accessing email. You should be able to use use any working IMAP or POP library for Python to download your email. If you want tag/folder information, you'll need to stick to IMAP.

As far as I know neither libgmail nor gmail.py are compatible with the current version of Gmail. I use IMAP to download mails from gmail. Python's imaplib module is quite useful for this.
