Error in sending e-mail from Contact Us page

[Del]

I am new to Web design and using Zen Cart. I have the book “e-Start Your Web Store with Zen Cart” It has helped me in the design of my web page Delsand.com.

I have the following problem when sending the email from the “Contact Us” page.


When in the “Contact Us” page and with the required fields entered, you click on the send button the following error is generated:

500 Error - Internal Server Error
This error was caused due to an unexpected difficulty in fulfilling the user request. The most likely cause of this error is a crashed or error'd CGI script or program. Please verify that the program is properly compiled and/or operational and carry out any necessary debugging.

Action taken:
Check it out on different PC to assure that the error was not with the default mail program.

Checked to assure other emails were being generated correctly and they were, Order confirmation, Welcome, Order status changes, etc.

I deleted and replaced the file “tpl_contact_us_default.phpfile” in the zencart/includes/templates/thestore/template_default/templates with the original one from
/zencart/includes/templates/template_default/templates/

I am still getting the error has anyone else reported this problem? Do I need to contact ix web hosting?
Any direction on this would be welcome.

Problem solved, thanks to a link to other similar problems:

DrByte wrote on 20 aug 2006. “ in reply to another contact email problem "In Admin->Configuration->Email Options->Contact Us Pulldown .... what happens if you leave this blank?”

That was the problem I had a bad syntax for my drop down list:

I had
[email protected], [email protected]
It should have been blank or
Sales<[email protected]>, Support<[email protected]>
I did not follow the correct syntax as was documented on the Set "Contact Us" Email Dropdown List

"On the "Contact Us" Page, set the list of email addresses , in this format: Name 1 <email@address1>, Name 2 <email@address2>":

Thanks to DrByte and those answer posted problems for the help
