I think everybody on here is constantly keeping an eye out for what to host next. Sometimes you spinup something which chugs along nicely but sometimes you find out you’ve been missing out.
For me it’s not very refreshing or new: Paperless-ngx. Never thought I would add all my administration to it. But it’s great. I probably can’t find the thing I need, but I should have a record of every mail or letter I’ve gotten. Close second is Wanderer. But I would like to have a little bit more features like adding recorded routes to view speed and compare with previous walks. But that’s not what it is intended for.
What is that service for you?
For this, Bind-mounts are your friend:
Files get dropped in /srv/paperless-ngx/consume on the host and import to the container.
As far as setting up mail goes: it’s pretty straightforward. Add an account, then create a rule for each type of mail you want it to manage. Specify filters like who it’s from, what’s in the subject/body, how old is it, etc.
And until you are comfortable, just leave the action set to mark as read. Worst case, if you didn’t set your filters right; it’ll unnecessarily mark mail as read. No big deal.
I just have mine move processed mail to a folder on the mail server called ‘Paperless-Imported’, which I manually clean out now and again.
