lieer

I'm using lieer and mujmap to sync my Gmail and Fastmail accounts to a local notmuch mail storage on top of ZFS pool. That ZFS pool is in turn replicated off site. I use neomutt to access my archive over SSH. And notmuch is very fast at searching all of my emails. * https://github.com/gauteh/lieer * https://github.com/elizagamedev/mujmap * https://notmuchmail.org/

I don't use Gmail :-) You could use something like lieer[1] which will also sync your notmuch tags with gmail labels. If you don't want to sync the labels, I'm sure there are plenty of solutions out there to download Gmail to your local machine in a well known format like Maildir.

For GMail sync someone else has already mentioned Lieer which is an excellent tool for robust two-way syncing of emails and tags/labels between Notmuch (and anything that uses it) and GMail. It uses the GMail API so it doesn't rely on IMAP. https://github.com/gauteh/lieer

I fear this for my gmail. I now use mbsync (lieer[0]) to have my emails synced locally on my homeserver, and then browse it with notmuch[1]. It's an incredibly freeing experience to have all your email on your own machine. 0: https://github.com/gauteh/lieer 1: https://notmuch.readthedocs.io/en/latest/man1/notmuch.html

Put everything into a single notmuchmail database. It wil deduplicate the emails and even provide a fast local search interface for all of your mails https://notmuchmail.org/ For gmail you can use lieer to pull everything https://github.com/gauteh/lieer (tho it can take hours to pull everything). Fastmail has a similar tool https://github.com/elizagamedev/mujmap If you unpack tour mbox into maildir then you can import that too into notmuch After everything is in notmuch you can easily push your mail to fastmail with isync/mbsync https://isync.sourceforge.io/ As a bonus point you now also have a easily updatable local backup of your e-mails.

For Gmail you can use lieer. It uses Gmail API's to sync mail and labels between notmuch and Gmail. https://github.com/gauteh/lieer

Also see notmuch [1] for a frontend-agnostic tagging/search system that also works great for multi-gigabyte maildirs. I use it with the Emacs client and lieer [2] for populating the maildir and syncing tags with Gmail labels using the Gmail API, which is a lot more reliable than offlineimap for me.

I use notmuch[1] with lieer[2]. Notmuch maintains a tags database with full-text search indexing for a set of maildirs, and Lieer uses the GMail API to synchronize messages with a maildir and labels with notmuch tags. There are lots of notmuch frontends available, but I use the built-in Emacs frontend. [1]: https://notmuchmail.org/ [2]: https://github.com/gauteh/lieer

Thanks. I realized that I was just reading about GMail backups a few days. Here are some repos that I happened to star on GH. * https://github.com/gauteh/lieer * https://github.com/imapsync/imapsync * https://github.com/joeyates/imap-backup

For gmail backup, I use https://github.com/gauteh/lieer which stores the result in a maildir with labels synchronised with notmuch. It uses Google's API to fetch and send e-mails, and is quite performant.

If you're a gmail and a notmuch user, consider using lieer - https://github.com/gauteh/lieer. It uses the Gmail API to synchronize mail bidirectionally so that you can handle mail locally (except for muting threads). If any Googler is reading this, why oh why is muting not part of the API?

Would something like gmailieer[0][1] be affected? (Or, in general, FOSS software for syncing with one's gmail data.) It uses some of the "restricted" scopes[2]. Also, what does the verification as "non-malicious software" entail? [0] https://github.com/gauteh/gmailieer/ [1] A cli program that downloads one's (i.e. the user's) gmail e-mails onto one's computer (without touching any third-party servers on the way) — it's effectively a better offlineimap for gmail, for use with notmuch.[3] [2] https://support.google.com/cloud/answer/9110914#restricted-s... [3] http://notmuchmail.org/

If you use https://github.com/gauteh/gmailieer you can have bidirectional sync between gmail tags and notmuch tags. Personally, I don't bother with it. When I have to do mail on my phone, it's usually so limited in scope that I don't need to retain state when I sit down at my main computer. I can imagine that's not for everyone, though.

If you're using notmuch and Gmail, I'd recommend taking a look at gmailieer - https://github.com/gauteh/gmailieer. It uses the Gmail API to fetch mail into a local maildir and keeps the tags synced bidirectionally. The downside is that for whatever reason the Gmail API doesn't support the mute label, so having that tag sync is not possible. (If a Googler reads this, please fix that! For others, there's already an issue filed as referenced in the gmailieer readme.)

Another option is to keep a local mirror of your gmail, this can be one or two way and with or without tags. https://github.com/gauteh/gmailieer and http://isync.sourceforge.net/ are tools I've used for this. isync/mbsync is a high performance IMAP based syncing tool that works well with for large mail spools. gmailieer uses the gmail API so it only works with gmail but has good support for two-way tag syncing. Some advantages of this approach are very fast local access and and the ability to use your preferred local indexing and tagging tools (notmuch under emacs in my case). PS, I forgot that gmailieer is notmuch-only but I think some mutt users use notmuch for indexing so it could still be useful.
