Hi I wanted to know if there is a way setup a global or shared subdomain. What I wanted to do is allow all my customers to be able to access mail.theirdomain.com and pull up squirrel mail. I know this is possible I just cant figure out how.

Also I want to do this without having to setup it in each user account in the httpd.conf if possible.

Using subdomains for this just complicates things. While I'm sure you could manage to do it, I'd think offering them:

http://www.domain.com/mail would be easier to set up and would work just as good. Set up a symbolic link for all domains so that 'mail' goes to the place that you installed the mail script.

I have it setup that way now. I just wanted to make sure before I annouce it that I couldn't do mail.domain.com with ease.
