Storing old emails in the Cloud using Mail
Hi,
I use Mail as my email client for two Gmail addresses and a work email. This is probably a stupid question but can I store old emails in the Cloud. I've seen people with big lists of folders and when they're done with an email, they drag it into one of them ready to refer back to in the future. How do I set that up? Does it use iCloud? Am I an idiot for not being able to figure this out myself?
