  • Imapsync
    Instead of migrating from server to server โ€” and remaining on computers I donโ€™t own - I download locally which it looks this tool doesnโ€™t do. I use mbsync/isync which is fast and reliable. https://isync.sourceforge.io/. - Source: Hacker News / over 1 year 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

In particular I use isync to fetch emails via imap (that's independent from Emacs) and the Emacs extension mu4e to view, write and send emails.

  • How to run a script to cleanup emails ?
    Myself, I keep a local copy of my mail using isync/mbsync. This allows me to use mutt and notmuch on my mail, or even just plain old grep. Granted, this also means you'll have to download your 30GB mailbox locally. Personally, I consider this a feature, as it gives me a local backup. Source: over 3 years ago
