I am trying to use the 'Kernel::System::PostMaster::Filter::CMD' module to filter an incoming email so when the email is not found in my customer database it puts the email in the Junk folder Below is what I have inserted in my config.pm right after my server settings. My understanding is the script simply has to return a 0 or a 1 if a 1 is returned it will move the email into the Junk folder, can someone look over my syntax I have in my config? I know my script works, and returns a 1 when an email is found, but maybe my config syntax is wrong or in the script should I be exiting or returning 1? Meaning should I end with exit 1; or return 1;? Any help would greatly be appreciated. Rob Snipet from Config.pm: # Job Name: 5-noEmailFoundFilter $Self->{'PostMaster::PreFilterModule'}->{'9- noEmailFoundFilter'} = { Module => 'Kernel::System::PostMaster::Filter::CMD', CMD => '/opt/otrs/scripts/mysqlscript', Set => { 'X-OTRS-Queue' => 'Junk', }, }; Here is my script: sender_mail=`awk '/^(From.*<)(.*)(>*)/,gsub(/.*<|>.*/,"")'` retcode=1 sql=`mysql -N -B -u otrs -potrs otrs -e "select login from customer_user where email = \"$sender_mail\""` if [ $sender_mail != $sql ]; then retcode=1 else retcode=0 fi echo "this script has run $sender_mail and $sql and retcode = $retcode"

exit $retcode
