General problems importing PST and MBOX files.

[roswitina]

I have tried working with the program using two different versions of Open-Archiver, Proxmox - VM - Docker Container and Proxmox - LXC - Installation via Community Script.

When I connect IMAP accounts, both work very well. My problem is that I have a 21 GB Outlook PST file that I want to import. Even after 48 hours, the import is still not complete on either system, and the system itself is obviously overloaded and no longer allows login to the console, for example.

I therefore exported the PST file into two MBOX files (inbox and sent). I then divided these MBOX files into files of approximately 500MB each.

Importing these 500MB files into the LXC version works, but only slightly more than 400 of the approximately 750 emails are imported. To rule out errors due to deduplication, I imported the same MBOX file into Mailstore Home, which imported and displayed all 750 emails. I got the same result of 750 files with the Bichon product using the command line import bichonctl.

I was very impressed with Open-Archiver's search function, which is why I actually want to use this program. What is still holding me back is the import function for archive files, which, as far as I could tell, was far from complete. I have not yet been able to identify a reason for this difference.

Thanks for your post. I'll investigate this.

I also noted a similar behaviour with mbox files.
The mbox file was not particularly large, few hundred mails maybe 200 MiB in total.
From this, only a fraction of mails got imported.
It remains unclear to me why that happened, and why it stopped importing after a certain number of mails.
How to debug the state of such import process?

There is definitely a problem with the MBOX parser. I switched to zip files of EMLs instead, and that works well.
