copy of email goes to WP administrator

Running plugin v3.1.9, we are wordpress hosting and devs.

In the plugin settings, recipient’s email is set to our customer’s email address

Website General Settings Administration Email Address is set to our own support address.

Product enquiries are going to both addresses, as well as to the enquirer.

We are using Plugin WP Mail SMTP which makes SMTP connection to localhost postfix.
