PHP Mail daemon in France

Two major french society are using and testing our product. There are :
http://www.kalyweb.com
http://ff.st (will become a part of kalyweb)

They are using our services for the easy configuration (anybody can add a new domain to the SMTP) and for the support (we look often to the delivery queue to see if there is a bug...)

We will be happy if anybody want to help us testing our products and giving us help (kalyweb has started the web design of our future webmail).
