Sorry I know the title makes no sense.
I have a client who I am using gravity forms for, and they work fine test sending to myself, but when I change the address for the "send to address" to their email addresses, they don't receive the email.
They are talking with their host and need to know the actual mailing address that the email is coming from (my guess is mail.obhg.com? [their domain is obhg.com]).
Thanks in advance. I hope that made sense.
