Email cooc.com cn

It looks like you're trying to send an email to a Chinese domain (.cn) with a.com extension. That's not possible, as.com is a top-level domain (TLD) and.cn is a country-code TLD (ccTLD) for China.

To send an email to a Chinese domain, you would need to use the correct TLD, which is.cn. For example, if you want to send an email to a user named "john" at a Chinese domain, the email address would be "[email protected]".

If you're trying to send an email to a Chinese company or organization, you may need to use a different email address or contact method.
