Subdomain mapping to domain
- by bobobobo
What happens if you have 2 DNS entries:
Name | Type | Value
-------------+-------+--------------
example.com | A | 20.20.20.20
example.com | MX | mail.example.com
Does this mean that smtp requests to example.com will map to 20.20.20.20, and somehow request in the headers mail.example.com? What?
