With the cron task (help page
here) you have two elements, the timing and the command-line.
The timing, from the help is the
0 0 * * * part.
25 0 * * * would mean every day at 12:25am. Your host may allow you to enter it directly as shown or you might have to choose the minute, hour, days, etc. from drop-downs.
Unless your host allows you to enter an "advanced" line including the timing as shown in the help, the command-line should not contain *'s or numbers and should instead look like this:
/usr/bin/wget -O /dev/null -T 0 http://example.com/mail/dailymail.php?pw=YourDailyMailPass 1> /dev/null 2> /dev/null
Please let me know if I can be of further assistance!
