Sending emails through a GoDaddy hosted site is problematic at best.
Over the years, hear is the info I have been able to gather For GoDaddy:
1) The do not support the php mail() function on Windows hosted servers, only on Linux hosting plans - They are pretty good about changing your hosting plan over if you ask them
2) You will need to configure the linux server to use PHP 5 - They will help with this if you ask.
3) The smtp server to use is:
relay-hosting.secureserver.net
on port 25
4) They use a non standard implementation of Pear Mail that does not work in Universal Email.
