Sending/forwarding email using different "from" address on iPad
In Apple Mail app on my iPad (iOS 9.3.1) I'm not able to switch to different "from" addresses (corresponding to different servers?) when forwarding or sending email.In other words, only two of three potential "from" addresses are available. However, I am able to do so with all three addresses visible on my iPhone with the same iOS 9.3.1. Am I missing something in my settings?
