Inflex/sendmail NEWBIE

["Sheila R. White" <captaininvictus hotmail com>]

Redhat 7.2

I am trying to block ZIP files
What do I edit??? The inflex.cf or Inflex

This is what I added to inflex.
It didn't work. What am I missing? What is the correct procedure?

/usr/local/inflex/inflex script

{cut} -d: -f2 $fileresults | ${grep} -E "(MS-DOS|Windows
PE).*executable" >> ${typebadfileslog}

${cut} -d: -f2 $fileresults | ${grep} "PC bitmap data" >>
${typebadfileslog}
${cut} -d: -f2 $fileresults | ${grep} "AVI" >> ${typebadfileslog}
${cut} -d: -f2 $fileresults | ${grep} "MPEG" >> ${typebadfileslog}
${cut} -d: -f2 $fileresults | ${grep} "ZIP" >> ${typebadfileslog}

Thanks
