vacation program doesnt work anymore because of sendmail security?

Hi friends, after changing the righst of my sendmail from -r-sr-xr-x 1 root root 462412 Sep 6 01:17 /usr/sbin/sendmail to -rwxr-xr-x 1 root root 462412 Sep 6 01:17 /usr/sbin/sendmail which is because of security improvement, I cannot use the vacation program anymore. I did not find a configuration parameter to adjust the used mailer program in order to change it to a special version of sendmail with suid set which could at least get the vacation to run. Any ideas how to get the vacation to run anymore? Regards, Rainer --
