Not sending confirmation emails to admins

Joomla 2.5.8
HikaShop Essential 2.1.0

We are using the HikaShop user registration (with several custom fields). When a customer registers, they receive a confirmation email, but the admin does not. I know HikaShop uses the Joomla email settings, so here is what is currently set:

Mail Settings

Mailer *: PHP
From email: This email address is being protected from spambots. You need JavaScript enabled to view it.
From Name: admin's name
Sendmail Path: /usr/sbin/sendmail
SMTP Authentication: No
SMTP Security: None
SMTP Port *: 25
SMTP Username: (blank)
SMTP Password: (blank)
SMTP Host: localhost

The admins receive emails from other components on the site (contact us, newsletter sign-up, etc.)

Thoughts?

But there is no email sent when a customer places an order either. The only email the admin gets when an order is placed is the confirmation from authorize.net. Is there a way to set it up so that it will send an order confirmation email that includes all their registration info (all custom fields)?
