.
The Internet host name.
A list of the MX records found is placed into the array mxhosts
.
If the weight
array is given, it will be filled with the weight information gathered.

This function is now available on Windows platforms.
This function should not be used for the purposes of address verification. Only the mailexchangers found in DNS are returned, however, 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.
For compatibility with Windows before this was implemented, then try the » PEAR class » Net_DNS.
