getmxrr
(PHP 3, PHP 4 )
getmxrr -- Get MX records corresponding to a given Internet
host name
Description
int getmxrr ( string hostname, array mxhosts [, array weight])
Searches DNS for MX records corresponding to hostname. Returns
TRUE if any records are found; returns FALSE if no records
were found or if an error occurred.
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.
Note: 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.
Note: This function is not implemented on Windows platforms.
Try the PEAR class Net_DNS.
