My only improvement would be to loop on the call to 'recipient( )' and capture the results yourself. Please see below. 'recipient( )' does this internally, anyway. Good luck. -c 

#test_mail.pl

use Net::SMTP;
use Net::Cmd;

$smtp = Net::SMTP->new(
        Host => '192.168.55.173',
        Debug => 1,
        );
die "Did not connect to host..." unless defined($smtp);  #you can remo
+ve this, so it would die w/ your address
$smtp -> mail("root\@test-server.my.home");
@good = ();
@bad  = ();
@mess = ();
foreach $toadr (('good_address@my.home','bad_address@my.home')) { 
    if ($smtp -> recipient( $toadr,{ SkipBad => 0, Notify => ['FAILURE
+']})) {; #make result boolean, 1 ::= good
       push( @good, $toadr );
    } else {
       push( @bad,  $toadr );   
       push( @mess, $smtp->message() );
    }
}
$smtp -> data();
$smtp -> datasend("TO: good_address@my.home\n");
$smtp -> datasend("TO: bad_address@my.home\n");
$smtp -> datasend("SUBJECT: Test e-mail from root\n");
$smtp -> datasend("\n");
$smtp -> datasend("A test message.\n");
$smtp -> dataend();

print "These address(es) went: @good\n";
print "These address(es) were bad \[ and why \]:\n";
for (0..$#bad) {
    print "$bad[$_]  \[ $mess[$_] \]\n";
}
$smtp -> quit();
