proton-bridge VS ImapSync

That isn't really fair. If you read the article, protonmail essentially supplied the FBI the recovery email of the account. This is metadata that protonmail must have that isn't encrypted by the user for obvious reasons.

Regarding the "MITM" for every email sent, this is related to their "bridge" software which allows regular IMAP/SMTP software to use Proton Mail. This software must edit the emails to encrypt them in their scheme.

This software is open source and can be inspected and/or built locally. https://github.com/ProtonMail/proton-bridge

> This appears to be related to a behaviour that ProtonMail has of dropping all plaintext email if any mime-encoded parts exist.

I'm actually more shocked knowing that they drop plain text if there is a mime-encoded part (e.g. HTML). Just verified that all mails imported from GMail and all newer mails I received in PM only have the HTML part now, while GMail shows both HTML and plain text parts in message source. Great, now if I want to use a text-only client to read those mails in the future, I won't be able to.

Now I honestly wonder, how did they think this is something okay to mess up? Is there just no usable email hosting service for someone that want their mails not touched and also stored securely? Like, this is not even going to save storage space for PM - I'm paying for my storage.

The privkey is never loaded out of the keychain. Rather, it acquires a handle to the privkey and relies on the keychain to carry out cryptographical operations.

Oh yes. The Bridge shouldn’t have been marketed as stable for the past years because of this issue (see issue #220 on Github, reported 2021-09-29). It’s fixed in Bridge 3.0.

You see this https://imapsync.lamiral.info/ ? It's only for mails but it's a great solution.

I've had to do large email migrations before and honestly, imapsync is the way to go - https://github.com/imapsync/imapsync

Do your parents have a domain, or are they just using the provider's domain? I've set up my 1522+ to backup our mail accounts using MailPlus on the Synology, and IMAPSYC running on my lab server. But it's backup only, not archiving. That technology could be used to get to your desired state, but there's some work involved to make a secure connection from the internet to your Synology possible, sync/archive the mail, configure you parent's devices to find your device, etc.

Check out imapsync (https://imapsync.lamiral.info/) - I am using it since years and migrated tousands of mailboxes without any problems.

Check https://github.com/imapsync/imapsync

I would use https://imapsync.lamiral.info/ for email and sure there is another tool for contacts and calenders.

There are two solutions for this 1. Using a tool called imap-sync to sync all your emails (it has a great incremental sync). You can run it periodically via cron 2. Using the same or similar tool and export to a database.

If you want to sync from one IMAP server directly to another, there's also the very popular imapsync: https://github.com/imapsync/imapsync

Have a look at imapsync. Source: former web hosting sysadmin. Used this many times to move email.
