Unable to add multiple email address using same domain name

[Fizbi]

I wish to add two emails to my PayPal business account.

name_1 at mybusinessdomain dot com

name_2 at mybusinessdomain dot com

Notice that they are different emails from the same domain.

I am unable to do this. I can add other emails outside of mybusinessdomain dot com.

Is this not allowed? If allowed, how come I can't add the extra email from my same domain?
