My first thought is to dump it all into a Maildir-backed IMAP server, in which case you can bifurcate your problem into separate repository vs client problems. Apple Mail will happily talk to an IMAP server, as will most mail clients.
How new mail lands is another consideration. I'll admit I have not thought a lot about this, so maybe there is another obviously better solution. I have a postfix/dovecot set up, but I read the mail from that using Emacs/Gnus and it has its own Maildir, so mail doesn't sit very long in dovecot. -- Russell Senior [email protected] On Tue, Aug 5, 2025 at 2:49 PM Paul Heinlein <[email protected]> wrote: > > On Tue, 5 Aug 2025, James Tobin wrote: > > > Hi, > > > > I have a large MBOX (14gb).
