offlineimap VS Nextcloud

There are also isync and OfflineIMAP which sync email locally.

I'd consider using the Bridge + offlineimap (or a similar tool). That can connect via IMAP to both the Bridge IMAP and your destination IMAP service and copy all mails automatically that way.

As u/alex_herrero says, Proton Mail Bridge is very much useful. I'm using this myself together with offlineimap to have a local backup. I also use the Bridge with Thunderbird too, which also works quite well (especially the v3 beta).

For the sync / import functionality the MSP uses offlineimap, which is another counterpart to IMAPSYNC. Changing the import tool will not bring up the solution to the main problem, that I am not able to reset the imported stuff back to zero in order to test the different scenarios of the main use case.

Don't risk relying on someone else's hardware or service, use something like Offlineimap or Mbsync to sync your emails to your computer then automate multiple backups.

Many people use OfflineIMAP.

I've used offlineimap in the past: http://www.offlineimap.org/

I'm looking into replacing Thunderbird with mu4e (for the first time, despite being an Emacs guy for 15 years) and I got unexpectedly stuck at step 1, dowloading my email. offlineimap is broken on newer Pythons, getmail doesn't support Python 3 at all, and fetchmail is infamously inscrutable. It all seems a bit ridiculous, but I guess it speaks to how webmail has come to dominate proper email clients. Any recommendations?

Neither a mutt, nor an offlineimap user, but I believe those two are often used in combination: http://www.offlineimap.org/

It really is hard to leave Gmail when all of your data has been conveniently stored therein. This is one of Google's retention strategies and it is indeed brilliant.

That said, there's a vast number of self-hosted alternatives like Stalwart Mail (email) [1], Immich (images) [2], NextCloud (Google Docs) [3], etc.

NextCloud - GitHub

Good open source self-hostable alternatives exist! https://nextcloud.com/ (no affiliation, just a longtime happy user) is great for file sharing and even collaborative online document editing.

If you do not want to host your own instance, there are many great providers who will host one for you at a low cost.

See Configuration and syntax changes and Special packages. The latter this time includes changes around NextCloud 23 and Tor Browser prior to 12.5, both of which should be upgraded beforehand.
