I would like to REALLY archive some older e-mail-folders. Archive seems not to be the right word, because i work with empty inboxes, so every completed or answered e-mail is still archived in a folder (with the name of the year), but i use IMAP so all archived emails are still on the server.
Now i want to EXPORT the years 2018-2019 to my selfhosted-backup-server so that i can delete the emails on the mail-server.
a) Which format make most sense? EML? mbox? Another one? Would be nice if i can search the archived stuff without too many effort. b) Should i export directly from the UI of my mailprovider (if possible) or is exporting from thunderbird-client ok.
93000 mails since 2008 are just 2,1 GB. I have an archive on my home server where I also host my main IMAP server. I just move them from the inbox to Archives.YEAR.
Commenting because I too am interested in this. I also would like to see if anyone has solved the issue with Thunderbird and Yahoo email where only 10,000 emails are kept. I have an inbox with about 20+years of emails, and with the 10k cap, I realized Thunderbird was literally deleting the oldest ones. Since I wisely told it not to delete them on the server when it copied them, I didn’t lose them, but with that volume of emails, I really don’t want to have to manually move them into folders. Guess this turned into a ramble, but it would be nice to have a backup since you never know when one day you will wake up to be told service x is shutting down.
Hi,
i do a simple 1:1 backup with offlineimap, which saves the mails in plain text files (similar what you get when look at the source in thunderbird).
These files are backed up regularily with restic.
Both backups are running automatic, and on multiple machines…
MBOX is a standard format, which is text based, (like the emails themselves are) and should be compatible across multiple email clients. It can contain entire folders.
EML is also a standard text format, but usually contains a single email in each file.
In the worst case, you can just open up either one in a text editor if you need to find something.

I think that is the way I want to go! Thunderbird on my PC is the „central mail client“, so I just have to draw the archived years (imap) to a local folder. The advantages: If I look for an older mail, I do not have to search in seperate archived files (mbox/eml). And with backing up thunderbird, I have a backup of all my settings AND mails!

I’ve been meaning for years to set up a solid archiving system that I don’t have to manually babysit. I’ve had my eye on mailpiler (https://www.mailpiler.org/), but haven’t found the time to get up to speed on it. I’m the meantime, I drag messages to a local folder like a barbarian.
Interesting project! I’ll spin it up in the next couple of days and check it out
I’ve been using imap-backup for many years without issue, it backs up to mbox files that it can restore onto any IMAP server because it also stores IMAP metadata on the side. I then backup the dir itself using borg. It deduplicates and compresses so the backup archives themselves are extremely small.
That’s me! I got dovecot in docker working for email archive, and moved all my old emails there. I access them through thunderbird on pc and k-9 mail on phone. Works great!
It took a bit of time to set up the passwords, and understanding the configuration. I used the lets encrypt certs from caddy.
I had to look at some different examples of the dovecot config file to get it right

It doesn’t really matter, you should do it however the mail archive software wants it. Apparently there is a pretty big difference between eml and maildir, so you possibly need to try both ways to see what works with your software and workflow.
What email archive software do you use? I’ve often thought about spinning up an IMAP server locally that doesn’t send/receive but allows me to copy all my old mail to it. I have a dozen or more email accounts across different providers and would want each kept separate in the archive. They also span 15+ years.
What does the Thunderbird logo have to do with this?
My Lemmy-client forces me to add a picture. I was pretty sure to find a solution with thunderbird - what I did
I use getmail
You could use mbsync to automate this. You can configure it so that it downloads new mail with IMAP, but keeps them even if they are deleted from the server.
Then you will have a Maildir that you can manage with any mail client, index with notmutch, etc.
copy and paste it into a text file and stick it in a folder. I encounter an email that is worth archiving approximately once every year or so. Most just get deleted once they serve their purpose.
Sync to Thunderbird. Tools > Export.
I know it is not ideal, but it works as long as Thunderbird is around.
