NOTE: Based on CPANEL. This information is not currently endorsed by ListMail. Use at your own risk...
When a message is run by the cron, it will be REMOVED from the scheduler. If the cron ran and the message is still there, chances are your cron is not set properly.
Here is how I test mine (cron)....
(NOTE: I do not test with the Daily Mail feature as suggested by DW)
Create a test List and add an email address you use.
Create a message to be sent with the scheduler
I use cPanel for controlling my crons.
In cPanel, under the Cron Jobs list, the first option is to have a message sent of the output of the cron job. You want to put an email address to where the message should be sent.
Temporarily adjust your cront to run every minute or every other minute
You should start getting cron job messages and they should look something like this:
--14:23:01-- http://domain.com/ListMailPro/dailymail.php?pw=GoMonkeyGo
=> `-'

Notice the first line with pw? that is the password that is used to access the SMTP email server. This is the the same password you use when you set up the SMTP mail sending under "configuration"
For the cron to execute, this is the command line we use (remember, this is for cPanel on our Unix server
/usr/bin/wget -O - http://domain.com/ListMailPro/dailymail.php?pw=GoMonkeyGo
Once you get an email from the CRON to your email account, you know the cron is running. When there is a message in the queue, instead of seeing "No scheduled messages", you will see what was sent. Be sure to set the cron to run at 12 noon/midnight. This is the best setting with this application, we have found.
Again, if you are using cPanel and you find that you are NOT getting the message from the CRON, be sure to check the error logs for a hint of what could be happening.
Hope this helps...
