Cfmail cf10 - "from" and "Username" must be the same?

Hi,

i am want to send from error@domain.com to the debugging team debug@domain.com using this simple code

<cfmail to="debug@domain.com" from="error@domain.com"

subject="sending error message plz respond!" username="sender@domain.com"

password="password-correct" server="mail.domain.com" type="html">

          bla bla bla bla blga    

</cfmail> 

the issue is that if the from is not an existed email account i get a verification error on mail log of coldfusion althouth the username is correct...  This used to work in cf8, did they now changed it?
