How to send a pre written confirmation email automatically when a customer pays?

Hello all,
I have no idea how to do this, hence the following question.
I want to send a pre written email automatically when a customer pays online for their order.
I remember reading somewhere that it is done via an autoresponder, is this correct?
If so, where do I find this so that I can use it, please?
I use Cpanel and I see that autoresponders are there also.
As I have never used such a beast, I have left well alone until now.
Any help would be greatly appreciated.
Regards

Zen Cart already send an order confirmation email when somebody pays and completes an order. Is this what you are asking about?

hello there,
yes it is.
Can I customise the wording of that email at all?
I did not realise that one was automatically sent.
regards

The general email text is in includes/languages/english/email_extras.php and that specific to the checkout success email is in includes/languages/english/checkout_process.php.

very many thanks for your help, much appreciated.

hello again.
I have just looked at the file which you mentioned in your last email and cannot find any way to edit what I want.

What I need to do is, on the email that the customer receives after purchase, is to edit where it says 'make your cheque payable to Store owner'
I want to insert my own name in there so as to have payments made out in my own name.
Is there a seperate file for this page that I need to edit, please?
many thanks again

in your zen cart admin
login and go to configuration -> my store

make sure that all that information is filled in

and then in admin -> modules -> payment-> checks edit and put the pay to and put the correct name there,

Yes, done it at last!
Very many thanks for all of your valuable help.

this can be used to send automatic emails based on a situation - e.g. when a customer paid (would need to do some coding)
