"cgi-lib.pl" is as dead as Perl 4. CGI is a much more robust solution that takes advantages of Perl 5 features (such as references). I would instead write something like: 
#!/usr/bin/perl -wT

use CGI;
my $q = CGI->new();

my $fax      = $q->param('fax');
my $email    = $q->param('email');
print $q->header();

error('Please fill in all the required blanks') unless
    ($fax && $email);

mail();
# print success method, redirect?

sub error {
    print <<HTML;
<HTML><HEAD></HEAD><BODY>
<H3>$_[0]</H3><BR>
</BODY></HTML>
HTML
    exit 1;
}

I'd also use Mail::Send or Mail::Mailer instead of opening a pipe directly to sendmail.

Title:
Use:  <p> text here (a paragraph) </p>

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
  • Posts may use any of the Perl Monks Approved HTML tags:
    a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, details, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, summary, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
