I would say only Mozilla Thunderbird!

The best arguments for a long-term mail storing solution - it keeps your emails and all your mail settings, in a form that is truly portable, so that you can easily move it from computer to computer

I am trusting it with 22 GB of emails (many tens of thousands of emails) organized in many folders.

You can have it connected to many online mail services, so it will sync (and keep an offline copy of your mail) and keep all of them separate. Or, you can configure it to sort all your email in a single place and folder hierarchy.

You can have various types of filters, separately per mail account.

Absolutely. I have emails in my Thunderbird profiles going back to 1996. No one can look at them unless they hack my systems and/or have physical access to them.

I highly recommend Thunderbird (download it now. You won't be sorry.)[0].
