The chinatelecom.cn domain is China Telecom's corporate email. It has strict anti-spam policies, and emails from that domain are frequently rejected or bounced by upstream mail servers due to the high volume of phishing emails originating from Chinese IP ranges. We have had cases where maintainers tried to reply to our chinatelecom.cn addresses and the messages were silently dropped, which is obviously not ideal for kernel development. That's why we use Gmail for kernel submissions — it's simply more reliable for getting patches delivered and receiving replies. We'll make sure the author identity and SoB chain are correct in future submissions. Thanks for your patience. Thanks, Jing
