I don't know anything about cgi-lib.pl
. However, if I were to
code this fascist-style, these thoughts would cross my mind:
Use the three-or-more-argument version of open. It's safer.
Turn $mailprog into a lexically scoped variable or constant
(use constant ...). Messing with it is unlikely, but I'm following my fascist mindset.
Passing improperly untainted data to sendmail screams SPAM GATEWAY!
