Error Cannot exec 'spammng'

Error Cannot exec 'spammng'

The error will look like "Cannot exec 'spammng......'":

Solution:
cd /usr/local/psa/admin/bin
rm spammng (make sure spammng is not present)

then create the symlink
ln -s ../sbin/wrapper spammng

Use the listing command to make sure the symlink is correct.
ls -la spammng
