MailStore backs up e-mails from your e-mail client or account and stores them in its own (compressed) database.
You can import your mail from Outlook, Windows Mail, Thunderbird, Exchange, as well as POP / IMAP accounts (such as Gmail and Yahoo).
It can re-export them, burn them to CD, search them and store your tree structure and the various accounts you've asked it to read.
This makes it possible to keep e-mail archives without necessarily weighing down your e-mail client, and to transfer e-mails between programs, since MailStore can also export all e-mails in eml format (which is universal), thus bridging the gap between different e-mail clients.
