Ha yeah it just needed its time. Two more quick question, it only works when I do webmail.myDomain.org, is there a way to make it work if the person was to type www.webmail.myDomain.org? Try making another host header value with www.webmail.myDomain.org and didnt work.
Can this CNAME trick work with any Host value? Say if I was to make a CNAME entry called test and then point that to @ and make a website with a host name of test.myDomain.org, would that work?
Thanks for your help though Tom, it's greatly appreciated!!
