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.

So this is 100% a really common situation. I don’t know any of my friends that aren’t hovering at about 96% of their gmail capacity and don’t want to pay. In fact that’s me today. Hence I’ve been looking around at self hosted alternatives and had previously looked at extracting my emails from Google and loading them in from local storage into Thunderbird - However I was playing around with Yunohost today and randomly uncovered this page - https://yunohost.org/es/email_migration I’m not sure how relevant it is but points to potentially some approaches. I can’t vouch for them but I’d love to hear from anyone who has used imapsync or larch
If you selfhost paperless-ngx, there are option to add email accounts and regularly import emails+their attachments like any other document. You can then have it delete imported mail from the mail server, or just move/mark it so you can deal with that manually.
It doesn’t currently support OAuth2 for providers like Microsoft, so you’ve gotta use App Passwords with Gmail for now, but there is a fix in the pipeline to add OAuth2 support soon. (there’s also other methods you can use to get that part working right now)
I wrote this ansible role to setup dovecot IMAP server. Once a year I move all mail from the previous year from various mailboxes to my dovecot server (using thunderbird).
I don’t think you want a mail server, you want a mail archive. A quick google search for “selfhosted email archive” shows a number of good leads.
I think that that is right that I fundamentally want an archive, not what a normal mail server provides. Part of my thought on looking at mail servers is that those would integrate directly with whatever other front-end/client that I’d normally use, whereas an archive maybe would not.
And regarding archive-specific stuff, I am seeing some things on a search, but I guess i’m wondering if folks here have any recommendations. When I look at , for example, nothing comes up for email archive, just for email servers. That, plus what I see when searching, makes me think that the archive-specific stuff is either oriented to business or oriented to a CLI (like NotMuch, which was mentioned in the discussion here and does look cool).
As another poster pointed out, it sounds like you want more of a mail search and archival tool than a mail server. I would suggest you pull the emails in maildir format from Google Takeout, and then index/search them with the amazing Notmuch. Notmuch is way more capable than Gmail search ever has been. Look at the Arch Wiki page page as well for info, the official docs are a bit obtuse but it’s not actually hard to use.
This looks like a good backend for sure, but the web frontends look a little lacking and I’m not seeing anything about a mobile frontend (other than if a web one was up, which would be fine). Have you tried any of the web frontends?
No, I used it with Alot mostly in the terminal. Can’t really speak to the front ends, I was kind of assuming you don’t need to search your old emails that often.
I had roughly the same goals ( archive search 2 decades of mail) but approached it completely different: I export every mail to PDF with a strict naming convention.
- Backend: No mailserver, just storage and backup for files.
- Search: based on filenames FSearch and Void tools Everything. I could use local indexing on pdf content.
- Frontend: a pdf viewer.
Pdf? You converted plain text to something designed to preserve formatting? But why?
You could use maildir and find things with “grep” or any mail client like Thunderbird.
