Hi thoer!
Are you sure cron jobs are supported by your host? Do you see the feature in your web hosting control panel (where you set up email accounts and other aspects of your hosting).
If cron jobs are supported but your cron job still isn't runing, there could be a problem with the /usr/bin/wget utility ListMail uses. Here are two alternative command-lines you might try:
The 2 alternatives are "fetch" and "curl". With example commandlines as follows:
(example for 11:57pm)
57 23 * * * /usr/bin/fetch -o /dev/null -T 0
http://www.site.com/ListMail/dailymail.php?pw=YOURPASS 1> /dev/null 2> /dev/null
57 23 * * * curl -o /dev/null
http://site.com/ListMail/dailymail.php?pw=YOURPASS 2> /dev/null
For your testing, set the timing to
* * * * * so that the cron task runs every minute. Enable "send report to admin when dailymail runs" on the ListMail Config page. When it's set up correctly, you should receive a dailymail report every minute, after-which you can modify the cron task to have the correct once-per-day timing.
Regards
