Since I store all the email I ever receive, I have a gianormous storage folder. To make things more managable, I have them split up by year. The eds.org mail server runs the old uw-imapd which stores things as flat mbox files in your home directory. I figured, I wasn’t going to be changing my archive at all, so I set the file permissions on these to read-only. It turns out that my mail client, Apple Mail.app, couldn’t download the email from those folder via IMAP. So I recently discovered that if I set the file permissions to read/write, then it can download everything. Arg, annoying…
