Hello,
if this is really copy/pasted then there is something wrong with the “header”.
Look at the plugin again.
if [ -x /usr/sbin/amavisd-agent ]; then
echo '<<<amavis>>>' <----
echo '[ps]'
/bin/ps ax | /bin/grep '[a]mavisd'
echo '[agent]'
waitmax 5 /usr/sbin/amavisd-agent -c 1 | grep -v ^$
fi
It should output
<<<amavis>>>
not
<<>>
