Unable to send SMTP emails from iOS/iPadOS when not connected to Cox network.
Similar to issue here: Unable to send SMTP emails from Outlook when not connected to cox network. | Cox Community
Basically, when I am away from home and connected to WiFi/Internet from a different telecom, my outgoing email does not work. When I am on my phone connected to Verizon wireless, it works fine. But (most recently) when I am connected to my daughter's in-home WiFi in Washington state, the outgoing email fails. This was when she was with Charter/Spectrum before and still occurs with the new ISP, Ziply Fiber. This happens at other locations as well. And since my iPad does not have a cellular plan, I am never able to send emails from that device when I am not at home. This is really problematic as I do most of my work from my iPad when travelling.
PLEASE HELP!
