       This function should not be used for the purposes of address
       verification.  Only the mailexchangers found in DNS are returned,
       however, according to <A
HREF="http://www.faqs.org/rfcs/rfc2821"
TARGET="_top"
>RFC 2821</A
>
       when no mail exchangers are listed, <CODE
CLASS="parameter"
>hostname</CODE
>
       itself should be used as the only mail exchanger with a priority of
       <TT
CLASS="literal"
>0</TT
>.
