Mismatch email validation rules between basket and order

Steps:

1. Create a basket with all required info to place an order
2. Update customer information for a basket with email: "qwe@qwe.qwe"
3. Call order creation with such basket

Actual result:

'{"title":"Invalid Customer Email","type":"https://api.commercecloud.salesforce.com/documentation/error/v1/errors/invalid-customer-email","detail":"Invalid customer info 'email' address."}'

Expected result:

From my understanding there 2 options for how functionality should work:

• Make same validation for customer email for basket
• Remove validation during order creation

Additional information:

Order with the same email can be placed for the SFRA-based site
