What is eMail Cruiser?
 
eMail Cruiser is a web email access tool that allows you to access to mail servers from your web browsers to send and receive your emails.

eMail Cruiser is built by using Servlet, JSP, JavaMail, HTML and JavaScript, but no applet. Therefore, it can be run on any platforms which can run Java, including Windows NT/2000/98, Linux, Solaris, AIX, HP-UX, etc.
