I have a customer at work who has an ipad and an imac. she uses the mail app on both. Both use imap settings not pop3 Inbox emails she says show on both. junk/spam show on one or the other (im guessing which ever one goes online first) can I sort this? she needs all emails on both devices. imac is always one and auto checks email every 5 mins. some of her emails get miss sorted and junk/spam so needs them. her email is with bt if it helps.
