Introduction to Zend_Mail
A big thank you to Ryan Horn for putting together this great screencast about Zend_Mail. Ryan took the time to talk about how to setup a dev environment that uses a gmail account. This is perfect for folks like myself who work in a development environment that’s behind an annoying ISP firewall on SMTP (port 25). Ryan Horn is a web developer based out of Buffalo, feel free to reach him by email.
