NOTES
Note This function should not be used for the purposes of address verification. Only the mailexchangers found in DNS are returned, how- ever, according to RFC 2821 when no mail exchangers are listed, $hostname itself should be used as the only mail exchanger with a priority of 0. Note For compatibility with Windows before this was implemented, then try the PEAR class Net_DNS.
