Webmail Question

How Do I configure it so that webmail.customersdomain.com appears and it has links to login to there e-mail, I want a static page here, then they would follow links to login to the email client of there choosing that has been installed.

 

Im not quite sure how to proceed, under that directory am i spose to put the HTML file or what in scripts/wwwacct (i had no postwwwacct is that correct?) What do I do to automate it create a directory with the static page in it or what?

Also is there a way that I can make it so it doesnt show up and count towards there subdomain total. IE they cant remove it or anything, its just automatic with every account?

What I would really like to do is to be able to change the http://www.yourdomain.com/webmail into a page of my liking, and then remove the secure access login required, and then just move it to http://webmail.yourdomain.com and they can use either or http://www.yourdomain.com/webmail is this possible?

 

Bump Anyone
