It really amazes me how many newbie Perl hackers:
(1) ignore the CGI Security FAQ (especially the parts about perl), or
(2) roll their own mail sending stuff, instead of using Net::SMTP
    or the more powerful Mail::Tools package, both found in the CPAN.

On second thought, maybe it's not amazing. :-)
