Sorry if this is explanatory, but I've searched and can't find the answers. Is Archive mail only Gmail related? I accidentally changed some settings and have no idea what they were on before? I'm worried it may mess up what stays on the MacBook when using emails on the iphone. The blacked out is the domain name of my email domain. Should the Mailbox behaviours all look like that, and Archive Mailbox be on my iphone? On the Archive page, should it be 'on the server' as opposed to on the phone again? What does it archive and where, if it's deleted stuff, that goes in deleted no? Mainly, the pic on the right, If I ticked on the server, archive mailbox, where would it go, I have no Archive mailbox on my MacBook in Mail? What are the standard settings for this?
