Protecting email files in my MAIL app?
My server host (HostPapa.com) tells me I've gone way over my limit for mail up on the server. I never access my mail via the server, didn't even remember it was being stored there. I just want to go into my HostPapa account and delete all those old emails. Which I thought I could do without issues, because they are all collected in my Mail app on my MacBook Pro, backed up of course with Time Machine..
But! The server host tells me (because my email is IMAP and not POP) that if I delete all the email up on the server the next time I log online the server will 'sync' with my computer and automatically DELETE ALL THE EMAIL FILES ON MY COMPUTER.
Not good. I've got 10-15 years of business files in my Mail. I'm wondering if there is any Apple way to make sure the data on my computer cannot be touched by the server's automatic sync system. Any way to turn it off IN my MacBook? I want to continue to get the emails in Mail from the server obviously. But without them being saved indefinitely on the server and causing me to go over my limit up there. Ideally I'd like to be able to delete them on the server the moment they are on my computer.
All ears, Ben
