Setting up a new web site on centOS 5 box

There are so many great tutorials on the web about setting up a Linux box for web hosting, but why not add one more… right? Actually this tutorial is written specifically for a co worker that is not familiar with Linux, so this tutorial is being offered to “assist” him with the migration process. His old hosting company provided him with CPanel and he is reluctant to change, but who in their right mind would pass up hosting at the price of “free ninty-nine”.

Dealing with sendmail errors

I noticed last week that my emails were not being delivered properly. After taking a look at when the issue started, I realized that it was about the same time I updated my box.

My email was being returned with the reason: 550 Banned rcpt apache@localhost.localdomain. There was also another error 554 5.0.0 Service unavailable. Both of these errors on their own were not to helpful. I asked a friend (the one who sold me the box) to help and he gave me some good advice, but I was unable to resolve the issue and several Google searches didn’t reveal any solution.
