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.
