Contact from not sending to a particular domain

Hello,

I have a site where the enfold contact from isnt sending any emails to an address on the same domain as website.

I have three email addresses set up in two forms. The two email addresses that are not on the same domain as the site are receiving the emails of forms submissions. I need to have the from send emails to the address on the same domain (my customer). Is there a way to get this to happen?

Thanks in advance!
