I am not familiar with binmode. Is it something to do with encoding? Below is my code where i think the problem might be.

my $msg = MIME::Lite->new(
        From => 'fromid',
        To => "toid",
        Subject =>'Web trial for today',
        Type => 'multipart/mixed',
);

$msg->attach(
        Type => 'application/vnd.ms-excel',
        Path => '/root/Webtrial.xls',
        Id => 'Webtrial.xls',
);

my $mailer = new Net::SMTP::TLS(
        'smtp.gmail.com',
        Port => '587',
        User => 'username',
        Password => 'xxxxxxxxxxx'
);

$mailer->mail('fromid');
$mailer->to('toid');
$mailer->data;
$mailer->datasend($msg->as_string);
$mailer->dataend;
$mailer->quit;
