Yet another question about self-hosting email, but I haven't found the answer at least phrased in a way that makes sense with my question.
I've got ~15 GBs of old gmail data that I've already downloaded, and google is on my ass about "91% full" and we know I'm not about to pay them for storage (I'll sooner spend 100 hours trying to solve it myself before I pay them $3/month).
What I want is to have the same (or relatively close to the same) access and experience to find stuff in those old emails when they are stored on my hardware as I do when they are in my gmail. That is, I want to have a website and/or app that i search for emails from so-and-so, in some date-range, keywords. I don't actually want to send any emails from this server or receive anything to it (maybe I would want gmail to forward to it or something, but probably I'd just do another archive batch every year).
What I've tried so far, which is sort of working, is that I've set up docker-mailserver on my box, and that is working and accessible. I can connect to it via Thunderbird or K-9 mail. I also converted big email download from google, which was a .mbox, into maildir using mb2md (apt install mb2md on debian was nice). This gave me a directory with ~120k individual email files.
When I check this out in Thunderbird, I see all those emails (and they look like they have the right info) (as a side - I actually only moved 1k emails into the directory that docker-mailserver has access to, just for testing, and Thunderbird only sees that 1k then). I can do some searching on those.
When I open in K-9, it by default looks like it just pulls in 100 of them. I can pull in more or refresh it sort of thing. I don't normally use K-9, so I may just be missing how the functionality there is supposed to work.
I also just tried connecting to the mail server with Nextcloud Mail, which works in the sense that it connects but it (1) seems like it is struggling, and (2) is putting 'today' as the date for all the emails rather than when they actually came through. I don't really want to use Nextcloud Mail here...
So, I think my question here is now really around search and storage. In Thunderbird, I think that the way it works (I don't normally use Thunderbird much either) is that it downloads all the files locally, and then it will search them locally. In K-9 that appears to be the same, but with the caveat that it doesn't look like it really wants to download 120k emails locally (even if I can).
What I think I want to do, though, is have the search running on the server. Like I don't want to download 15GBs (and another 9 from gmail soon enough) to each client. I want it all on the server and just put in my search and the server do the query and give me a response.
docker-mailserver has a page for setting up Full-Text Search with Xapian, where it'll make all the indices and all that. I tinkered with this and think I got it set up. This is another sort of thing where I would want the search to be utilizing the server rather than client since the server is (hopefully) optimizing for some of this stuff.
Should I be using a different server for what I want here? I've poked around at different ones and am more than open to changing to something else that is more for what I need here.
For clients, should I be using Roundcube or something else? Will that actually help with this 'use the server to search' question? For mobile, is there any way to avoid downloading all the emails to the client?
Thanks for the help.
If you arent an actual journalist who is being personally, specifically hunted then you probably don't need to take the same precautions as one.
And yea, the guide boils down to "none of these things are 100% safe but they are realistic things you can do that can offer more protection than not doing them."
Your skimming of the article missed how they do indeed talk about the shortcomings of every suggestion they have. For example, the article also does indeed talk about how you can turn off gps but your phone will still ping towers revealing your location, and goes on to say that you can put your phone in a faraday bag but that isnt practical for most people but is indeed an option if you want to do it.
