I got an error while setting up an site, which is having some changes with their file names (Diff. in Upper/Lower case).
[Thu Oct 31 00:29:59 2013] [error] [client x.x.x.x] script '/var/www/www.abcd.com/wwwroot/mlbteamstandings_data.php' not found or unable to stat, referer: http://demo-abcd.xyz.com/index.php?option=com_content&view=article&id=86&Itemid=839
So, issue has been resolved by adding apache2 CheckSpelling and CheckCaseOnly module into the virtualhost file.
<VirtualHost *:80>
ServerName demo-abcd.xyz.com
DocumentRoot /var/www/www.abcd.com/wwwroot
<Directory /var/www/www.abcd.com/wwwroot>

Send Mail Configuration : Disable Local Delivery

What I did to disable local delivery. I'll be using the example.com domain.

Requirements:

  • example.com A entry pointing to IP address assigned to one of the eth interfaces.
  • /etc/hosts defining example.com assigned to the very same IP address as above
  • example.com MX records pointing to Google servers (ASPMX.L.GOOGLE.COM, etc)
  • default sendmail installation (mine was on Ubuntu)

For changing the mail hosts name from your local machine name to domain name.Setting the hostname in sendmail.

If you need to change the hostname that Sendmail announces itself as, just add the following to sendmail.mc:

define(`confDOMAIN_NAME', `mail.yourdomain.com')dnl

For example-: Your domain name is www.xyz.com, then

define(`confDOMAIN_NAME', `www.xyz.com')dnl
