4.4 Configuring Mail to Go to One Server and the Web to Another
want mail addressed to a particular domain name to be routed to one
mail server, while users specifying that domain name in a URL reach a
web server on a different host.
mail servers sending mail to a particular domain name mail
destination preferentially use MX records for that domain name, add
an MX record to that domain name pointing to the mail server. Web
browsers, on the other hand, only look up A records, so attach an A
record to the domain name pointing to the address of the web server.
foo.example. IN MX 10 mail.foo.example.
foo.example. IN A 192.168.0.100
This is less a recipe than a reminder that a single domain name can
serve multiple purposes: it can represent a mail destination when it
appears on the right side of an email address. It can represent a web
site when it appears in a URL. Since some of these services look up
different types of records, you simply attach multiple record types
to a single domain name to accommodate them.
