I have emails from 1997-98 onwards all in one massive inbox, currently on gmail with emclient on Mac as the mail client (there have been probably a dozen services starting from self-hosted in the beginning). I would like to archive the historic mails for the first 25 years, but in a way that's actually searchable and usable in the future (and potentially importable to a new mail client/service) and not in any particular mailbox format that may go obsolete. There is no good reason to hoard them, other than "I feel like doing so". What are the best options, and tools?
For converting emails into archival formats, the two open source tools I'd look into are ePadd and Mailbagit.
If at least some subset of these emails are things you'd like to explore making searchable/viewable by the general public, I run fwdeveryone.com and am happy to chat.
Thanks. Will check out both ePadd and Mailbagit.
Unfortunately, there's no really publicly accessible content in these mails. At least none that I can classify in any meaningful way through a filter or search criteria.
Personally I prefer to have email history online in the form of a local IMAP server like Dovecot. It is saved in maildir format where each email is a separate file.
I can then use an email client to move emails and folders between accounts.
Make sure to have backups. I assume you currently don't have a backup, if it sits in gmail.
I was looking at mbox ... would you be able to recommend a simple (ideally, read-only) client which we can use to open and browse/search the mails in a mbox, without importing the content into a regular mail client.
Mbox is text, so it is searchable with something which takes a huge file. Not sure you will find client type formatting as standalone option. I use Thunderbird which is at least local.
