Please bear with me if I seem overly ranty on this point:
DO NOT INSTALL formmail.pl ESPECIALLY ON A SYSTEM EXPOSED TO THE PUBLIC
INTERNET - IT’S A MONSTROUSLY HUGE SECURITY RISK.
See http://www.monkeys.com/anti-spam/formmail-advisory.ps for the security
advisory; if you’re running formmail.pl in any capacity, please replace it
with the more secure version at ftp://ftp.monkeys.com/pub/formmail/1.9s/ or
disable it as soon as possible.
Apologies for shouting but there is at least one anti-spam DNSBL devoted to
blacklisting sites running formmail.pl. I reviewed the formmail.pl code a few
years ago and found a number of very serious flaws; sadly, it hasn’t changed
since then. Basically formmail.pl turns your mailserver into an open relay
which is then trivially exploited by spammers. I’ve received spam via
formmail.pl scripts; this is not a theoretical problem.
Regardless of firewalling and other security measures you may have in place,
it’s a very bad idea to install known unsecure scripts like formmail.pl,
especially when there are plenty of secure alternatives available. You are
better off coding your own special-purpose web-to-mail CGI script, taking
care to hard-code or programmatically generate recipient addresses.
Please don’t take this as a personal attack. Formmail is a unfortunately very
popular and many people don’t know its lineage - they find out the hard way.
I bear a particular grudge against formmail because it’s so obviously broken,
it has been for a long time, and the author either doesn’t have the talent or
time to fix the code or the common sense to stop distributing it. IMHO,
Matt’s Script Archive gives a black eye to every responsible open-source
developer out there and I feel sorry for everyone who has installed formmail
in good faith, mistakenly believing that the author took reasonable security
precautions when designing the code.

Is it possible to integrate RT to an existing web form where clients can
select which issues they want to report besides using the e-mail? Here’s
Web form -> client selects issue, describes problem, enters e-mail &
other contact information -> client clicks submit report -> server
accepts request, checks for required fields -> sends e-mail to RT -> RT
responds to client by sending back the trouble ticket
You should be able to do this with a simple web form, and something like
the formmail.pl script from Matt’s Script Archive.
