I use mbsync to pull down my IMAP stuff. https://isync.sourceforge.io/mbsync.html As how to get that *back* into the format an apple email client can use, not sure, I'd try to suck down a small imap db from somewhere, and then try to read it with your client. > > We do have an immediate need: downloading seven years of emails via IMAP = from her server at Rackspace, which we are leaving because the company fail= ed spectacularly in a ransomware attack and is unworthy of customer faith. = It has taken most of a week so far to download 390,000 emails, and we would= like to speed that up. I'd setup mbsync in the cloud somewhere, and suck things down into that, then rsync it down to your laptop. This would give you all your email, quickly somewhere else. I have 80Gbs to spare on most of the 15 boxes I have, if that would be enough? If so, let me know, I can help you set that up. Send me an ssh key? It is vastly more possible nowadays to run your own email server using a docker container, btw, that does all the right things out of the box. I am fleeing the cloud on this front as fast as I can. > I'm less lucky, since my mail (unlike hers) was on the Rackspace Exchange= server, which was the target of the attack.
