Notes

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.
