IMAP and sorting
I have a bunch of "on my Mac" mailboxes, for which I use rules to sort my in-boxes into subject areas. But because they are only on my laptop, they aren't visible on my phone or iPad once the rule has operated.
This is not good, since I generally sort stuff I care more about — from my family, about my son, topic areas I'm passionate about.
I could try sorting at the server level, but that seems very time-consuming, and the tools at my ISP aren't as good as on my laptop.
I could switch to Pop, so they'd be sorted and still undisturbed on the server. But then I'd have to go into each of mail clients and delete all the stuff I've sorted on my Mac.
Both of those options are unattractive to me.
I'm looking for suggestions on retaining my ability to sort off-server, while seeing the results of those sorts on all my devices. TIA.
