Hey emufarmers , Thank you for your reply
I still think I will try to use the mirror thingie , I've been looking in the wiki late yesterday and I found this :
"A mirror domain is a server alias on the DreamHost server that allows you to access the same DreamHost site content under more than one address. For example, you can have both a .com and a .net site that share the same site content, or access your site live before your domain is set up, using a dreamhosters.com subdomain."
It's a bit tricky to set due to the robots.txt but it's no biggie , so I think saturday night I will set both my .net and .com to DH dns and then set .net as fully hosted in panel and then .com as mirror see what happens , the reason I want this is I want customers to use seamlessely one or the other without being forced to redirect , I will check your option if it doesn't work , thnx again .
I have set a google app mail yesterday already with a less sensible domain and it's working great as far as I see , the only problem I had was it won't accept webmail.mydomainname.com as valid redirect , but I see it's reserved in the panel , I don't know if there is a turn around for this . it wouldn't let me create a 'mail' redirect subdomain either which was weird so I finally settled with 'email' .. that's not a big problem for me since I use this internally but I would still like to know if I can do something to get 'webmail' or 'mail' working instead like I have in my other hosters .
