I don't remember seeing any code in the HOWTO for forwarding. Am I supposed to use some custom Apache directives or something?
You can use the forwarding provided by ISPConfig ( http://ispconfig.org/downloads/manual_en/manual_kunde_en_src.htm#4_2_3 chapter 2.3.2), but if you need something different, you can use on of the methods shown on http://www.stevenhargrove.com/redirect-web-pages/ .
I followed the RoundCube tutorial I can't get webmail.domain.com working...Do I have to create DNS and DNS-MX records for it in ISPConfig?
bve32k, You have two options: First: Create a New Site with hostname like 'webmail' and check Create DNS. Second: If you already have the www host. Go to ISP Manager -> Your Reseller->Your Site Folder->Your Site, edit your site in Co-Domains, add a new Co-Domain, insert your new hostname (webmail) and the domain, check the Create DNS flag. Go to Forward tab and point your RoundCube Install folder (like /roundcube). I do the second way... Vinicius
Thanks..that worked...The other problem was that I am going through godaddy.com still and if you go to Total DNS Control and MX Records for the webmail records in there where it says points to..I put webmail.domain.com when I should have just put @.
