i just installed f-prot (needed for qmail-scanner) and i noticed that the f-prot.sh is wrong f-prot is installed in /opt/f-prot but the file f-prot.sh refers to /usr/local/f-prot/f-prot so the only thing that is needed is to fix the path (best way would be with a var somewhere)
unexpectedly away; reassigning
I have updated the patch to include a fix for f-prot-sh. Thanks for the bug report!
