Your cron task appears correct. What is the timing you have set up?
Once per day at 1:15am looks like this:
15 1 * * *It's possible that your host has disabled the program
/usr/bin/wget, used by the task.
It's also possible that your dailymail password does not match. Try copying and pasting the password from your task to the ListMail Config page. Don't forget to save.
Enable the dailymail report and set up your Admin Email. If things are working you should receive the report and your followups should be sent/processed.
