Import 100,000 emails into Proton
Hi,
New proton user here (paid version on Windows).
I have a large collection of past mailboxes that I use as archives but I need to access them semi regularly. So far I was using thunderbird straight out of the .mbox filtes but it's quite slow and only accessible on my computer.
I was hoping to transfer all those emails on proton with bridge on IMAP. Turns out it's incredibly unreliable and slow. Even a batch of 500 crashes after 200ish emails. And it takes 2-3 seconds per email.
Is there any other way to import those .mbox files into proton? (I don't mind if it's slow and takes days, but I don't want to have to manually intervene every 5 minutes because it crashes or have ot break it into 10,000 batches)
Thanks
