1. Google:
site:mail.ru -inurl:http://mail.EN -inurl:https://mail.EN -inurl:http://www.mail.EN -inurl:https://www.mail.EN

mail.ru of course, change your domain.

2. Using AXFR query to the DNS.
Not all DNS servers support it.

In General, the guaranteed way to get a list of subdomains for a given domain is not.
The search engines may not know about all, but AXFR is often prohibited for security reasons.
