Hello dearest Apple folks, Recently I was cleaning up my MacBook Air (2012) and I found out that my mail folder is actually larger than 13 gigabyte. Since my Air only has a mere 64 gb of harddisk space, I was wondering.. Is there any way I can reduce this size? Think of it like the way the Mail app in iOs works. I'd like it that way: the newest messages are stored on the device, the older ones are stored on the server and you can still search them. Thanks in advance!
