CEO,<BR>This is a formal email. We are the Domain Registration Service company in Shanghai, China. I have something to confirm with you. On March 27, 2026, Yahui Ltd submitted an application to register "reproducible-builds" as their internet
keyword and Chinese domains (reproducible-builds.cn,
reproducible-builds.com.cn, reproducible-builds.net.cn, reproducible-builds.org.cn). But after reviewing it, we notice this name conflicts
with your business name or trademark. In order
to deal with this matter
properly, it's necessary to send a message to you and
confirm whether this company is
your distributor or business partner in
China?</SPAN></DIV></SPAN></DIV>
