I am having a few issues that I need some help in resolving. I am using CENTOS 5.1 following the LAMP perfect server install, followed by the Virtual Users And Domains With Postfix, Courier And MySQL (CentOS 5.1) The only thing I left out of the LAMP install was the email portion due to the 2nd tutorial. I then loaded ISPconfig. My intent was to then use roundcube as the frontend for the Virtual Users, but when i created roundcube it created it's own backend. which is fine. Now I can still login imap/pop3 to the virtual setup, but I can't send any email. which has me confused. Does ISPConfig change your smtp server name? The second issue is with hosting multiple sites. When I tried to set-up roundcube I go a webpage from ISP config stating a shared IP address How do I fix this? I am completely lost at this point and am not sure where to begin to fix it all. Thanks ahead of time for any help.
