I say a few threads and put together some code as you can see below. I want to be able to determine if an address is valid: both the domain and account name. I don't really care if one or the other is valid, if either is invalid, then I consider the address to be invalid.

The code below is not very good, dispite several hours of work. eee@eee.com is ok. It does fail on addresses where there is no valid domain, but my code does not determine if the user account is valid. Before I continue to rack my brains, can I actually determine if a given email address is valid? Can Email::Valid or any other module actually call the mx daemon at ee.com to see if the given account, eee, is valid?

I continue to look, but am beginning to realise the best way is to talk directly to the smtp port directly, but I fear the code could develope into a nightmare...I sense this is really easy and I am just missing the point. Can someone hit me with a 2x4?

Please advise,

Simon

if($EmailAddress) {
        eval { 
            if (my $addr = Email::Valid->address( -address => $EmailAd
+dress,
        function start() {
                document.forms[0].elements[0].focus();
        }
        </SCRIPT>
        </HEAD>

        <body bgcolor='ffffcc' onLoad='start()'>
        ";

generate_form();

my $EmailAddress = $cgi->param('EmailAddress');

if($EmailAddress) {
        eval {
            if (my $addr = Email::Valid->address( -address => $EmailAd
+dress,
                                                  -mxcheck => 1,
                                                  -fudge   => 1 )) {
                print "$addr OK\n";
            } else {
                print "$addr failed $Email::Valid::Details check.\n";
            }
        };
        warn "an error was encountered: $@" if $@;
}

print end_html();
