I have just set up Roadrunner Mail on the Mac, which was harder than I expected. My old PC machine has the email messages that I wanted to keep- anywhere from 5 years old. How do I get these messages onto my Mac Mail? I could forward all of them (there are thousands), but this would take a while, and it would look like all of them were from myself, not from who really sent them. I also thought of somehow putting them on a USB drive, but the USB port does not work on the PC. When I set up Gmail accounts, they automatically put the old messages into my Inbox, but this is not the case for the Roadrunner account. How do I get these messages to my Mac Mail?
