Hey Daniel,

many thanks for this interesting pull request! I'm not very familiar with Gmail RSS, can you elaborate a bit what the advantages over conventional imap gmail are? And is this a Gmail for workgroups only feature or does it work with free Gmail as well?

Thanks for taking a look!

This backend works when IMAP access is turned off. Corporate customers of G Suite can disable IMAP access. Without IMAP access, conventional mailnag backends don't work. This backend gives users access to desktop email notifications even in organizations where IMAP access has been disabled by policy.

And is this a Gmail for workgroups only feature or does it work with free Gmail as well?

The linked documentation (https://developers.google.com/gmail/gmail_inbox_feed) suggests that it's a G-Suite-only feature, but the feed link (https://mail.google.com/mail/u/0/feed/atom) works with my personal account too, so I think the feature is just generally available.

Thanks for the fast reply! I see, so since it uses plain old http to fetch the mails, this also seems to be the solution to some of those firewall/VPN bugreports I got. Awesome, will do an in-depth review as soon as I find time!

Thanks. IMAP access is still preferable though: this mode is read only (no mark as seen), had no push support (so we have to poll), and in my testing reports only the 20 most recent messages. It's better than nothing though
