Comment (by brambo123):

 There are more options than just $_SERVER!['SERVER_NAME'] and
 php_uname().\\
 The functions get_site_url() and get_home_url() are also very suitable.

 In addition, there are more prefixes than www., for example: staging. and
 dev.\\
 By using getmxrr() it is possible to find out if the domain name is valid
 to send mail from.
