RustedNut, you can try a fresh install if you wish and see if you get the same problems. Any errors reported are appreciated, although it's more work and headache time for me!, it's the only way to ensure that all works as intended on as many different platforms and configurations as possible.
The suggestion of a verification code to avoid signup bots is certainly a good idea. I will add this on once all bugs and issues have been fixed in this latest release. Thanks for that idea.
The issues with table column sizes is being addressed now. Don't forget that you can also still see full text even of not showing in the table by hovering the mouse over the text.
As far as quotas go, I too get quota:unknown at the bottom of the inbox. This issue is not related to Admin Panel.
The way the quotas work in Admin Panel is that when a user signups for an account, the default quota set at install is written to a database table along with other user information and the account is created.
Admin Panel then reads this value from the table, thus dipslaying the quota that was given on account creation.
If the quota is then changed in Admin Panel both the account quota and the quota value in the database are updated with the new value, again synchronising the actual account and database values.
So, the quota that Admin Panel displays is basically a copy or reflection of the values that CPanel itself has. They are not taken directly from CPanel as not all servers support getting quotas.
