Mailman by Cool Focus
Mailman is an email-sending Flash applet that works with an ASP or PHP script (included) to send mail from a web page. You can control how visitors use Mailman: allow email to be sent to any address, lock the applet to a single email address, or set a list of allowed domains. You can also set a list of contact aliases, such as 'Sales Inquiries', 'Support Requests', etc. These are shown in a drop-down list, letting visitors choose which department to contact without seeing or typing addresses.
