E-Mail can often be the lifeblood of an organization and the majority of modern corporate e-mail systems are run by Microsoft Exchange. You can find dozens of books and pages upon pages of documentation regarding the Microsoft recommended best practices for the implementation of your Exchange system.
Although reading a least a few resources on this topic is a good idea, you can skip some of the guess work by using the Exchange Server Best Practices Analyzer. This tool runs a complete scan on your Exchange topology and compares what it finds to the Microsoft best practices. This will ultimately help your Exchange implementation as it will provide better performance, enhanced security, and possibly add a little bit more knowledge to add to your repertoire.
