Postfix mail server procedure
CentOS Community, I was wondering if anyone had a good resource or procedure for a step by step in installing a mail server with Centos. There ARE documents on google, however almost all that i've found were outdated from 2005. Does anyone know where I can find this type of document for a mailserver Postfix + MySQL + SpamAssassin + ClamAV + Squirrelmail + Postfixadmin, etc?

6.2 - How to check for a failed disk using LVM with a hardware RAID (3ware)
CentOS Community, What commands can I use to check the disk health of the system when LVM2 is being used on top of a RAID 10 using a HARDWARE 3ware raid card. The OS sees a hardware raid usually as one big drive. Is there a way to check the disks individually to see if any are failing, or throwing hard or scsi transport errors?

LVM question
CentOS Community, It is to my understanding that the /boot partition should never be placed on LVM and should be a physical partition on the hard drives (or on top of a RAID array). Is this an accurate statement? Also please advise if the SWAP filesystem is safe to be placed under LVM, or if this should be a hard partition / hard limit as well. I am unsure if boot issues or any filesystem issues

I know this was discussed before, and I have seen a million ways of doing this via online docs.

6.2 How to change hostname for each individual IP
Good day, I was wondering if there was a way to change the hostname for each individual IP address allocated to a system. For example if only one NIC card is being used (single port) and the hostname of the machine is "example.example.org", this hostname is being displayed for all applications no matter what IP I set the application to BIND to. My server has multiple IP addresses

CentOS 6 yum Groupinstall vs Manual install
Gentlemen, I have a question regarding yum groupinstall vs just using yum install. I have been reading tutorials online (for example how to run a Centos LAMP). Most of the tutorials have examples to install httpd, mysql, etc using yum install httpd.... The reason for this e-mail is that I noticed in yum grouplist that there is an option to install Web Server, MySQL database server, etc.
