Unknown Accounts

On Domains & Accounts -> Management -> Options ->Unknown Accounts

Is the option when arrives a email to the domain and the email address is incorrect.
You have 3 options:

• Reject mail
• Forward to (Catch-all) 
• Delete mail.

We are interested on mark two of them.
Reject mail and Forward to (Catch-all) , because we will know if a customers send to a no valid email. We can contact they and tell the address they send is not correct.

There is any way to mark two of the options?

Best regards,
