Submitting forms on GoDaddy email addresses

Is there any known issues with forms that are submitted to emails the run through GoDaddy?

I have 3 forms that are sent to an email address. When I test the forms using my email address it works great. When I use my client's email address it doesn't make it through. The only difference is that my emails run through 1&1 and theirs runs through GoDaddy.

Any suggested remedies?

No there shouldn't be an issue with emails sent to godaddy email addresses. They may have different spam filters... do they show in a spam folder on the godaddy email box?

Who is the email sent FROM? is it from a domain managed by GoDaddy? Is the FROM address an active working email address?

Ray, thanks for the response. I found the solution just a few moments ago on one of the Webassist forums and they are working great now. For anyone who my see this post here is the solution.

This is a GoDaddy issue only:

SMTP Host is relay-hosting.secureserver.net, port is 25, and "From" address must be an email address with the same domain, and if you want to reply to the sender use advanced settings and pass the sender's address dynamically. The form is sent within seconds.
