OK... Here's some suggestions.

#!/usr/local/bin/perl
Turn on Taint checking, warnings and strict.

#!/usr/local/bin/perl -wT
use strict;

for your header you can use the CGI.pm

CHANGE
&html_header("It's been sent");
TO

use CGI;
my $q = new CGI;
print $q->header;

Not that it matters much in a script this small, but I would point you to Template Toolkit to seperate you markup from your code. Then you can replace all these print statments.

    print "<H2 ALIGN=center>It's been sent!</H2>; 
        print "<HR ALIGN=center>";
    print "<IMG SRC=\"http://www.iupui.edu/~webtrain/Graphics/Photos/b
+ora_bora.jpg\>";
        ...

Here it looks like you're getting the query string. You can use CGI's param method.

CHANGE

@pairs =  &url_decode(split(/[&]/, $request));
while ($pairs[$r]) {
    ($a,$b) = split(/[=]/,$pairs[$r++]);
    ($name = $b) if ($a eq 'name');
        ($email = $b) if ($a eq 'email');
        ...
[download]

TO

$q->param('name')
$q->param('email')
...
[download]

And as merlyn pointed out this is really bad

open (MAIL, "|  mailx -s \"Web mail from $email!\" cholling\@iupui.edu");

but when you turn on Taint checking this will not be allowed. This does not mean Taint checking is the be all, end all, you can unsafely untaint data. I would highly recommend Ovid Web programming with Perl course.
