lfwmail is a lightweight webmail program. It will run with acceptable speed even on a Pentium 100Mhz Linux mailserver. It has just basic features and no calendar or folders, but it is fully MIME capable and can handle attachments. It is also very secure when you use https encryption. It converts HTML messages to ASCII for security reasons, but you can still see the HTML versions if you want. The code is clean and structured. The installation is straightforward and doesn't require a lot of non-standard modules.
