Installing things like perldesk (the email feature)

[Vidar]

I don't know if it's possible on hostrocket, but certain cgi-scripts like perldesk use an email feature, but in order to activate it, you must do something like this:
"You must setup your mail software (e.g. sendmail)
so that emails sent to the address(es) of your
choice are piped through to email.pl"

I was wondering if this is possible, if so, how?

Thanks.
