I would like to add cron job to check server ip on blacklist.
something like
curl 'http://mxtoolbox.com/SuperTool.aspx?action=blacklist%3a142.11.193.83' | grep 'you are on a blacklist.'
wget 'http://mxtoolbox.com/SuperTool.aspx?action=blacklist%3a142.11.193.83' -Oq- | grep 'you are on a blacklist.'
But it only download page without waiting mxtoolsbox checks.
What curl/wget request will be correct in this case?
