How does this look:

It looks awful.

$foo++  # increment $foo

# Greet the user
print "Hello!\n";

If ($foo =~ /bar/) {  # If $foo contains 'bar'

Don't comment what is obvious. Don't explain what code does. Explain algorithms, explain strange things. But don't insult the reader. If someone wants to know what a certain operator does, that someone should use the documentation.

Always assume that whoever reads source code either knows the language, or wants to learn it.

Further comments:

• Don't parse form fields yourself if you don't know how to. There are many modules that you can use for this.
• Don't send mail this way. As merlyn already pointed out, ione can easily use your script as an anonymous mailer.
• Don't leave unused subroutines around. It's confusing. If you really want to have the code around, comment it out.
• use strict and warnings.
• Use a module that sends e-mail. My favourite is MIME::Lite (despite its name, it can also send simple plain text messages).
• Learn Perl before writing scripts that are accessible publicly. It's okay to write bad code, but it is not okay to write bad code that others can abuse.
