Using Paypal , after placing an order customer is directed to paypal , inputs the email CC information and etc and is directed back to magento where they choose shipping and then click on place order.

I am getting this error:

Failed address validation %1

In the system log : Failed address validation, Email has a wrong format
However Email is valid with Paypal email address.

Any help would be appreciated.

The full error is:

main.CRITICAL: Exception message: Failed address validation: Email has
a wrong format

Trace:
