Icloud+ Mail "Reply-To" address
I am attempting to setup my iCloud external mail, of which is through a hosted mail server (name cheap) and using the Icloud+ mail service for my domain and emails. I am attempting to setup my mail to have a "Reply-To" address of which I own be listed in my emails and I wanted to know if this is something that Apple accounts for, like Gmail does in their mail service. I have noticed that I cannot do this through Icloud+ and wanted to understand better the mail app and see if I could get a Reply-To address setup.
