Doug,
Thanks for the pointers. I used
.* cum .*
I just hadn't done enough testing yet. What does the lower case "i" do that
you added to that line? I added it to my /var/qmail/bin/qmail-scanner.pl
file and after doing "/var/qmail/bin/qmail-scanner.pl -g" gave it another
test and it seems to have made no difference. It's still not case
in-sensitive.
Thanks
Malcolm
