stop resending user password in autoreplies?

[guser]

Hello,

I have the following code in my email_autoresponder template:

<{if $settings[u_sendpw] == 1 && $user[userpasswordtxt] != "" && $user[loginapi_moduleid] == 1}>
<b><{$language[aremail]}></b><{$ticket[email]}><BR>
<b><{$language[arpassword]}></b><{$user[userpasswordtxt]}><BR>
<{/if}>

... the first time a user submits a ticket, they get an autoreply containing thier password details--this is fine. Then every time the same user submits a ticket after that, they get an autoreply containing thier password details again--this is not fine. I thought the code above would check to see if the user had already been sent thier password, and not send it again.

Can someone tell me what wrong?

Thank,
