hostname problem with her site

See this guide to delegating your domain. You'll need to copy all the existing records first, which I suspect you haven't done (I'm not seeing any records for your domain with Dyn).

Otherwise, this sticky covers remotely accessing services on your own network, they also list the information we need to help you further.

I got fixed the website forwarding problem, but can fix the email issue. I have 3 emails wit godaddy, that are: support@iwssecurity.com; joel@iwssecurity.com and bonet@iwssecurity.com , i can send email but cannot receive. I got this message when i send an email from other account to one of the ....@iwssecurity.com "Sorry, we are unable to deliver your message to the following address. No MX or A Record for http://iwssecurity.com"

I know that this is related to what you told me on your reply, but when i get to Mail Exchangers for iwssecurity.com Page. i dont know what to do from there.

If you want to use GoDaddy for your email then you need to talk to them to find out what the MX records you should use are. Unfortunately we can't advise you as to what the correct settings would be, since they may vary by customer.

Priority 10: http://mailstore1.secureserver.net Priority 0: http://smtp.secureserver.net

So you need to create 2 MX records:

0 http://smtp.secureserver.net
10 http://mailstore1.secureserver.net

Both against iwssecurity.com

does not get any email, and cannot enter to my webpage that im forwarding from godaddy

For your e-mail you'll want to add MX records, and for your website you'll want to add A records. See this KB article.
(Sub)domain names with an A record and behind a dynamic IP address need to be updated with the related IP address information.
