I'm using Gmail for all my mails but I would like to have a complete copy on my desktop.
On Windows I was using Thunderbird but on my MacBook I would like to be sure that Mail is downloading and keeping everything.
I know that if I connect by POP, Mail is going to download everything. But as my Gmail account is configured to connect by IMAP, is it downloading all messages to keep them offline or is it only linking to online data?
I have also disabled the attachments' download: now I have changed it and said I would like Mail to download all attachments. Will it download all the attachments from old messages? If not (it seems not), is there a way to make Mail download attachments from all old messages?
