I'm not getting order confirmations or receipts. This started a few days ago. I have been getting them for years. I'm on Mac (desktop iMac ,using Mac's own Mac Mail, and a MacBook pro, with both desktop Mac Mail and webmail). I know how to block a sender, but I've never had to teach my Mac to TRUST/ACCEPT an email address, so I don't know what that involves.
Thanks for any help.
