주의
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:
For compatibility with Windows before this was implemented, then try the
» PEAR class
» Net_DNS.
