Hi,

Does anyone know if the webmail that gmx.com uses is an off the shelf peice of software I can buy? I assume it is a custome peice of software they have written, yet I could always be wrong.

I'm familiar with these professional webmail clients...
atmail.com
zimbra.com

Anyone else know of any high end webmail clients?

I'm not interested in squirrelmail, horde, etc...

Regards,

Wyatt
