good point.. OTOH, on a unix system it's easy enough to drop a subshell and
do the lookup explicitly:
$domain = "att.com";
$l = `nslookup -type=mx $domain`;
@mx = $l =~ /mail exchanger = (\S+)/g;
for $item (@mx) {
@A = gethostbyname($item);
print "name = $A[0]\n";
print "aliases = $A[1]\n";
print "type = $A[2]\n";
print "length = $A[3]\n";
print "address = ", join ('.', unpack ('C4', $A[4])), "\n\n";
}
which is just one of the many reasons why i like working in unix & perl. ;-)
