A Local Email Archive for Linux: What to Check

If you want a local email archive on Linux, start with the outcome: can you still read a message after it is removed from the provider? A client’s synchronized Inbox does not prove that. You need independent retained copies, plus a way to restore them on another machine.

Choose by the job you need done

Everyday mail: prioritize reliable sign-in, sending, folders and a workflow you like. Add a separate retention plan if you intend to delete server mail.
Personal archive: prioritize saved message bodies, attachments, offline search and an open export format.
Terminal backup: prioritize repeatable jobs, authentication renewal, logs and tested restores. Check whether the tool mirrors server deletions or preserves earlier copies.
Company retention: check access control, retention policy and audit requirements separately. A personal desktop archive is not evidence that organizational compliance requirements are met.

A ten-minute trial with your own mailbox

Install the Linux build from the download page and connect one account.
Archive a small date range that includes a plain message, an HTML message, a sent message and an attachment. Use Archive, which leaves server mail in place.
Switch to Vault and disconnect the network. Read the sample messages and open the attachments.
Export a backup to a second drive in Backup & Restore. Confirm that you can open the ZIP and find the saved EML files.
Before committing your whole history, test the restore workflow and check that the provider exposes every folder you need.

What MailVault provides

MailVault combines a desktop email client with a local vault. Manual archiving is free. Archived messages use EML in a Maildir structure, and the app supports local search and backup/export. Premium adds scheduled workflows and the archive-before-delete operation. Pick it if you want to browse and retain mail in one app; use the trial above to check the actual account you care about.

Questions to ask any alternative

Can I open the files outside the original app?
What happens to the local copy if a server message disappears?
Are attachments downloaded, or only fetched when I open them?
Can I back up and restore without the old computer?
Does a scheduled job alert me when authentication expires or a destination drive is missing?
