VM 2.0.18a remove button in confirmation email

[polarfuchs]

Hi forum members!

In the confirmation email there's a button that is linked to the shop frontpage and will open the actual order informations. How can I remove this button?

I don't want to offer any user registration or user account.

Virtuemart 2.018a is installed on J 2.5.9.

Thank you from polarfuchs
