DiskStation Email Import sucks

I have spent a few hours trying to import a backup of my old mails from Thunderbird into Synology and I’m willing to admit defeat for now. While I have no problem using the outdated version of Roundcube the my DiskStation ships with, I have a very real anger directed at arbitrary settings of 32MB and 20 files that keep me from importing my mails without going bonkers.

I came as far as debugging the UI while uploading and skipping their stupid-ass checks on the client, but there seems to be a limit of 32MB imposed by the server as well. So now I have a folder of eml files on my server in case I need these emails again, but I might not bother importing them into my DiskStation.
