Ricardo,
Alright, I received your information and have fixed your installation!
1. A field added at the last update wasn't applied to your followup table. I checked the upgrade script and its all there as it should be. I also tested this before releasing. I don't know why this certain command didn't take, but the rest of them did. I manually applied the command adding the new field to followups (for the new cron-style timing).
2. Bounce processing was disabled on your ListMail installation. Enabling it allowed the existing configured bounce script and Mail Forwarder to do their job.
3. The dailymail password set up in the cron job in cPanel did not match your current one in ListMail. If you change the Dailymail password you must also update the cron job.
4. I set up the new auto-resume script (
http://listmailpro.com/help/autoresume.html) to run once every 20 minutes.
That's it! You should be all set now. cPanel is known to work well with ListMail. :-)
Regards
