  • Imapsync
    Instead of migrating from server to server — and remaining on computers I don’t own - I download locally which it looks this tool doesn’t do. I use mbsync/isync which is fast and reliable. https://isync.sourceforge.io/. - Source: Hacker News / almost 2 years ago
  • Seeking Advice on Backing Up Emails from External Email Providers - Not Hosting
    There are also isync and OfflineIMAP which sync email locally. Source: over 3 years ago
  • Suggestions for long term email storage
    I set up mbsync to mirror the current (last 90 days) of my Fastmail IMAP account into another local Maildir, and told Notmuch to index that as well. This ensures a Notmuch search will cover both current & archived messages. Source: over 3 years ago
