contact no longer receiving my emails
One of my mail contacts has suddenly stopped receiving my emails being sent from my iCloud address using macmail. They are using aol mail on a windows 10 system. I sent another mail, again using Macmail, with an alias iCloud address and they received this. Why would this be please?
We are both on each others contact list, with no filters. My mail isn't even reaching their Spam. I'm receiving everything they're sending me.
Thank you
