php form will send to gmail but not other emails

I’m having a really odd problem…

I purchased a script off of Code Canyon to send an email form. The submission works if I use my gmail account as the receiving account but when I change it to the email it is supposed to go to it stops working, even though the form says it was successfully submitted.

Any ideas on what’s going wrong?

Thanks!
