Ask Slashdot: Best (or Better) Ways To Archive Email?
An anonymous reader writes: I've been using email since the early '90s and have probably half a million emails in various places and accounts. Some of them are currently in .tar files, others in the original folders from obsolete or I-don't-use-them-anymore mail clients. Some IMAP, some POP3. You get the picture. I don't often need to access emails older than a year or two, but when I do, I have found that my only hope for the truly archived ones is to guess what Grep combo might find the right text in the file ... and then pick through the often unformatted, unwrapped, super ugly text until I find the email address or info that I'm searching for. Because of this, I tend to at-all-costs leave emails on servers or at least in the clients so that I can more easily search and find.
My question is whether there's any way to safely store them in a way that I can actually use them later, offline, in a way that allows for easy date searches, email address searches, and so on. Thunderbird for example has 'Archive' as an option, but if I migrate to a different client I assume that won't work anymore. So what ways to people archive emails effectively? Or is this totally a lost cause and I should keep limping along with grep?

Use the Thunderbird archive.

Nope! :-)
I have about 10 years of email in Thunderbird. It keeps data in the mbox format which is a well supported open standard. The files are human readable and can be greped. There's lots of 3rd-party tools that support mbox. Thunderbird builds indexes (maybe those are proprietary) which are good enough that I can search that decade of email in a few seconds. (Maybe that is only searching by subject, to, and from. Message body searches might take longer). I remove attachments from old mail though, because that eats up space and is not valuable. If I needed the attachment, I saved it somewhere more appropriate.
The Thunderbird archive feature merely moves the mail into separate mbox folders to keep the main file from getting too big. It doesn't make them proprietary.
The hard part might be moving existing mail into that format from whatever it is in now.
Holding your business emails too long is a liability risk... they are subject to discovery in the case of a lawsuit. Most businesses have a limited email retention policy for that very reason.
