People have explained what's wrong with your web code. Now I'll explain what's wrong with your mail code!

An SMTP message is made up of a series of headers, followed by a blank line, followed by the body of the message. Just putting a blank line in your Perl source code is not sufficient to put a blank line in the e-mail message...

By and large, you should avoid talking to sendmail directly. Use a Perl module instead to save you from having to worry about the nitty-gritty details. Here's how you could send the message with Mail::Sendmail:

use Mail::Sendmail;

sendmail(
  To      => $to,
  From    => $from,
  Subject => $subject,
  Body    => <<END_OF_BODY,
Name: $name
EMail: $email
Address_line_1: $address1
Address_line_2: $address2
City: $city
State: $state
Zip: $zip
Home_Phone: $homephone
Work_Phone: $workphone
Type_of_Business: $business
Goals: $goals
Comments: $comments
END_OF_BODY
) or print "Failed to send message [$subject] to [$to]: $Mail::Sendmai
+l::error\n";

Hope this helps.

update: corrected a silly bug in the heredoc syntax (forgot the <<).
