On a list I have some DHS.gov subscribers. If a non DHS person sends to the list they receive the mail. However if the [log in to unmask] sends the mail the dhs.gov spam detection flags it as a spoofing attempt as the dhs.gov from address in the list email is coming from outside the dhs.gov domain.  I only have this issue on lists with dhs.gov subscribers. Is there a setting in it I need to change? I've looked through the help files and don't see anything yet. 

thanks nate
