I think this is what has been frustrating me & my friend with SSL Certificate regeneration with OpenSSL. Possibly the instructs need to regenerate the postfix pem stuff. Mail is controlled by the .org site I originally installed ISPConfig 2 as the first site. I now want my mail to be controlled with the domain with the same name but a different domain because it's a .net extension. Not the .org extension. In short, my mail is controlled by web1 which is domain.org & i want it to be controlled by a later added name which is domain.net without messing things up. I'm using debian lenny upgraded from etch, ispconfig 2, postfix & courier, as well as roundcube.
