I have a simple script to send an email posted below. It works fine from laptop#1 but fails on laptop#2 with "Service not available". Both are WinXP, #1 with perl 5.8.8 and #2 with perl 5.10.

It seems like something may be preventing communication on #2 somehow. However, the Mail::Sender docs give no clue to what that error message might mean. #2 was running VPN so I shut that down and no help. Neither are running a firewall.

Does anyone know what that message might really mean? Or what else I might check? Script is:

use Mail::Sender;

my $sender = new Mail::Sender;

if ( $sender->MailMsg({
        smtp    => 'my.smtp.net',
        from    => 'myaddr@myhost.net',
        to      => 'myaddr@myhost.net',
        subject => 'test',
        msg     => 'test',
    }) < 0 ) {
    print "Bad: $Mail::Sender::Error\n";
} else {
    print "Mail sent\n";
}
