File under: "Things that make me go 'hmmm'"

Before we get started: you KNOW what song I'm hearing.

Now back to our regularly scheduled piffle....

Since forever my email in-boxes have been very different on my iPhone and my Mac.

Specifically, some stuff appears in my phone's in-box but not my Mac's; others emails appear in my Mac's inbox and not my phone's.

Sometimes emails appear in both, but that's the exception rather than the rule.

Almost everyone I know would try to "fix" this: me, all that would happen if I tried to do that is 

1) I'd fail

2) I'd end up screwing up my email such that some emails would never appear on either device, or worse:  I'd irreversibly break my MacMail such that I'd have to hire/pay someone to fix it, costing me time (my most valuable commodity) and money.

Status quo works for me.
