I'd appreciate hearing (reading!) people's thoughts on making web form
data safe for using to compose an email via sendmail.
Basically, see comments in pseudo-code below, what should I be doing to
the data to make it safe?

use strict;
use CGI;
my $query = new CGI;
my $example_data = $query->param('some_form_item');
It depends. If you are going to send a plain text message, and the user
submitted data is only used in the body of the message, I can't think of
anything particular. OTOH, if one or more parameter is intended for the
message headers, there are a few things to consider.
