This function should not be used for the purposes of address
|
|
verification. Only the mailexchangers found in DNS are returned,
|
|
however, according to <link xlink:href="&url.rfc;2821">RFC 2821</link>
|
|
when no mail exchangers are listed, <parameter>hostname</parameter>
|
|
itself should be used as the only mail exchanger with a priority of
|
|
<literal>0</literal>.
