All, We were able to resolve this issue by NOT sending the following domains through our web proxy servers.
*.icloud.com *.apple.com *.google.com *.gmail.com *.googleapis.com *.gstatic.com *.yahoo.com Christina Klam Network Engineer Institute for Advanced Study 1 Einstein Dr Princeton, NJ 08540 +1 609-734-8154 [email protected] From: "C.

With IOS 13, people are no longer able to send or receive emails from google or yahoo through the Mail app. If they try accessing gmail or yahoo mail through the specifically branded app or a web browser, everything is fine. We have narrowed down the issue even further. The problem only happens when the iPhone is using a proxy server. We even tried bypassing the proxy all together for p*-mailws.icloud.com, but that has not helped.
