I'm currently using IMAP to access mail stored at my web host. But since space is limited, I'm considering a move to Gmail. Up until now, I've once every three months or something moved all current mail from my IMAP server to an offline backup, maitained in EagleFiler. This download has been done with help of OS X's Mail.app.
Now, one of the reasons switching to Gmail is that I can have more old mail available in the cloud. But I still want a local backup as well. As things were before, this was easy. I imported copied all mails online to EagleFiler and then deleted them off the server.
But what about my new scenario, where I want to add new mail to EagleFiler but leave them on my Gmail account as well? How to keep track on what's in EagleFiler and what's not?
Interested in OS X-based workflow for using Gmail together with EagleFiler. Thanks in advance.
