I want to put my Maildir into Nextcloud, and have my Nextcloud host fetch and index new mail.
Is it possible to do this without running a Nextcloud client on the host machine? I have mail archives going back to the early 2000s totaling around 15gb. My Nextcloud host is small, so avoiding doubling the storage like this would be a big win.
I know where it stores all the files, but everything is owned by www-data, which complicates things a bit.
