Hi I’ve searched high and low for this info without success. Does anyone have a guide on how to manually backup and restore all Mailboxes and Mail.app account info on El Cap? I’m having to do a wipe and clean install. My existing El Cap upgrade has gone badly. When I reinstall I know that my iCloud account will come across fine. My confusion relates to reimporting my other POP mailbox and account settings. How can I ensure a solid backup/restore? Thanks for any pointers.
