There is no mailing list data on disk.
I also checked those two database schemas, no data in those schema.
So I imported some mailing list from kloxo, and I could see the mailinglist showing in panel,
but still not able to add additional mailinglist.
I wonder there are some access issues, and wonder I can find the logs for the alert message
The alart message Alert: Create mailinglist failed [lists.xxxx.com on /home/lxadmin/mail] did not show much information
