FILE=/tmp/$$_outclam.tmp clamdscan - 1>$FILE

if [ $? -eq 1 ]; then STRING=$(grep "FOUND" $FILE |cut -d: -f2) zenity --warning --title="Evolution: Virus detected" --text="$STRING" &

exit 1 fi

exit 0

{% endhighlight %}

Now setup Evolution's Incoming mail filters to pipe mails through your newly created script. If the return value is not zero, a virus was detected and you might want to move the mail to Trash or a special folder.
