postfix/smtpd[XXXXX]: fatal: unsupported dictionary type: mysql, Postfix maillog Errors

I recently updated a development server running CentOS and ran into various minor issues including one regarding postfix being compiled with MySQL support. The development server runs ISPConfig for various virtual hosts and after upgrading all the packages on the server which included Postfix I noticed errors in the maillog. Below I describe what the error was in more detail as well as how it can easily be resolved.

Yum Error: Package curl-7.20.0-1.i386.rpm is not signed, Install A Yum Package That Is Not Signed

Today I have been working on a project for work that involved accessing FTPS using curl. I needed the curl –libcurl switch which is not available in curl 7.15 so I needed to upgrade curl on the CentOS server I was working on. The problem is that there are not any repos with newer versions of curl available so then I set out to create my own curl RPM package. I was able to do this while learning many things along the way such as signing RPM packages. The first revision of my curl RPM package was not signed but I wanted to go ahead and install it anyway so below I explain installing unsigned RPM packages using yum.
