The tel domain name and Chinese domain name cannot be used as the email suffix domain name.
The top-level domain names (com/net/cn/com.cn/), etc., can be directly used as email domain names to bind email addresses. Example: @abc.com. However, if your domain name does not point to the Alibaba Mail as required, your Alibaba Mail will not be able to send emails.
Supports binding subdomains to Alibaba Mail. Example: @123.abc.com
If you have opened an email service with the same domain name on Alibaba Cloud, you are not allowed to apply again.
Notes:
Please note that if you bind your email domain name as mail.domain name, or www.domain name, the resolution status will be automatically refreshed as the resolution has taken effect after the mailbox resolution is configured for the subdomain name. And the suffix of email address will be @mail.domain name or @www.domain name.
If you want to use the @domain name as the suffix, please use the top-level domain name to bind the Alibaba Mail, and then set the resolution as described above.
