I think Webuzo can be one of the best panel BUT is really a problem that this panel not support yet Antivirus and Antispam.
Maybe will support soon but it's almost to late, Webuzo Team should move before on the past for release this essential feature for manage well emails.
Sorry for my English.
Also hope maybe you can think in the future to change the one user panel and develop also a solution for manage other user, spaces because I want keep using this panel so if you add this feture to manage also other accounts... you have more people who can choose your panel!
And the support is amazing! Now seems replies on the Forum are better, price for the premium is ok, I suggest to mantain the same and I AM very happy with Support Team of Webuzo. They are kind and always serious are friends for me and I trust they.
The support is amazing, maybe the best.
