Most of what I'd say has been commented on already. However
I just wanted to remind you of the escapeHTML
function. It's quite good at what it does so you could replace
some of your code with:
foreach my $in ($message, $name, $mail)
{
$in = $q->escapeHTML($in);
# and of course you can do your subs here to:
$in =~ s/\(b\)/<b>/ig; # ...
}
The escapeHTML function is of course provided by CGI.pm.
It doesn't come with the :standard set
use CGI qw/:standard/; so if you want to use
it that way you have to include it
use CGI qw/:standard escapeHTML/;. This of course
is not an issue if you're using CGI.pm with its object
interface (as I have assumed above).
Remember that that $in in the foreach loop
is an alias to the elements in the list we've created. So for
the first iteration of the loop, $in is the same as
$message and everything you do to it is done to
$message.
You also might be interested in looking at Damian Conway's
Regexp::Common module as it has a very elaborate smut
filter that would save you having to write one of your own.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
