Problems with @mac email NOT being received by others
Recently people that I have been sending email to and they are in my address book have NOT been receiving a new email from my @mac.com account. The emails are in my Sent folder and show they have been sent. If someone sends me an email and I reply everyone sees it. But not a new email. Any thoughts on what I can do to find the problem?
I've cleaned up my email, rebuilt my inboxes. Please help!! I use my @mac for all my business!
Oh - this happens no matter where I send the email from - iphone 5 or Ipad or macbook pro.
Thank you,
K
