How do I move saved emails in "Mail" when I move from one ISP provider to another? Rogers to Bell
I want to change my ISP provider (from Rogers to Bell) but don;t want to lose all past e-mails I've saved there.
I also want to make sure everybody who has the current e-mail will be notified of my new one so I don't disappear before their eyes.
Specific steps would be appreciated!
MacBook Air, OS X El Capitan (10.11.1)
