Hey, first post here. I'm a Linux newb and these walk throughs are great. I was able to get the server up and running within a couple hours. I even got the server working in a RAID0 configuration (Ooooo...Aaaaa) However I would like to host multiple domains and multiple emails per domain. From what I have read the easiest way to do this is with Virtual Domains. I've found walk throughs for VDs but not for CertOS. Since I'm so green at Linux, I can't figure out how to get it working. I'm pretty sure I've screwed things up pretty good now cause I can't even connect to the SMTP server that I've just made...I don't get a response at all. I pretty much have my setup as described in the perfect setup, might be some small changes as I've tried to mix this setup with another and another to see if I can get it working. I'm sorry if this question has been asked before, I couldn't find it on google. Also, please bear with me as I'm very basic with linux right now and I can't wrap my head around being able to get this thing working. Thanks for any help you can provide! PS - On a side note, I ran into an error during install: # mysqladmin -h 127.0.0.1 -u root password password mysqladmin: connect to server at '127.0.0.1' failed error: 'Access denied for user 'root'@'localhost' (using password: NO)' Or in the place of 127.0.0.1 I had the server name but it didn't make a difference. Not sure if that will be part of the problem or not but I'm sure I did something wrong here.
