All my customer's first language is not English and also cpanel's webmail have problems for 2 bits languages, so I want to install my own webmail, but how to make it server wide? which when customer enter http://www.name.com/webmail

It will go to the webmail I install?

Thanks

:D

Add an alias in your apache config file. Something like:

Alias /webmail/ /path/to/install/www/

So , i nthis way, even new created account will go to my own webmail automatically without adjustment?

Thanks for your helps
