Q: can send but not receive mail from icloud

Isn't the simplest possibility that no one is sending you any mail?  Just saying.

I'm having the same problem. The issue is not receiving me.com mail, it's sending it through Mail. I sent a test email - worked fine. I sent an email to me.com from another email account and it won't come through, though I can go on icloud.com/mail and see that it indeed has arrived.

So something is up with incoming me.com emails and Mail. And Bruce is right - we can't change the incoming imap address - it is supplied by Apple when activating icloud in system preferences.

by "taking icloud online," I was able to receive iCloud emails in Mail.
