I have a shell script that I run setuid, which in turn calls a perl script that uses Mail::Sendmail. Since the shell script is setuid it causes full taint enforcement of the perl script. When I run my perl script I get the following: Insecure dependency in connect while running with -T switch at /opt/perl/lib/site_perl/5.8.3/Mail/Sendmail.pm line 293 Any suggestions to untaint would be appreciated.
