I have a Mail.app mailbox on my Mac where I archive mails received from an IMAP account which has a relatively strict quota on mailbox size (500MB). I write mails into the archive once a month (as I reach my quota), but I read from it frequently. The archive mailbox has grown to a couple of gig in size. Having just bought a second Mac, I'd like to share this mailbox across Mail.app on both Macs. Please can some suggest a good solution for doing this? I am reasonably happy to ignore concurrent access problems as a) I will almost certainly never make concurrent writes to to the archive, and b) concurrent reads should be ok for most systems that I can imagine.
My first attempted solution was to move the .mbox file to Dropbox and soft link (
ln -s) that file (actually a directory) back to its original location. However when I opened Mail.app the mailbox disappeared. Any suggestion on how to get this to work would also be appreciated.
