DevShed continues their look at the creation of a PHP email program (as excerpted from the "Zend PHP Certification Study Guide") with this new tutorial focusing on the management of the emails themselves.

In this second part of a two-part article, you'll learn how to manage email headers when creating a PHP email program, attach a file to a message, and more.

In this part they cover some of the details about the structure of emails, how to add an attachment to an email (for both a normal file and images for an HTML email), as well as a mention of how email is delivered.
