I think WebMail does

WebMail works by interacting with normal POP and/or IMAP and SMTP servers, this means
you can configure it to work with your current Email server in a matter of minutes.
It also means that messages read via these gateways are still available to be downloaded into
your user's normal Email client package. We recommend the use of the SurgeMail Server with
WebMail, but it can be used with any standard POP/IMAP/SMTP server.
With the NetWin authentication package NetAuth included with SurgeMail, you can also allow
users to create their own Email accounts from a web page. NetAuth can also be purchased
separately for use with other POP/SMTP servers.

WebMail consists of a set of template html pages, and a special CGI for processing these pages
and interacting with the POP or IMAP and SMTP servers.
There are template pages for:

Allowing an Email user to login to their Email account
Providing a list of new mail and processing messages
Sending a new Email message
Reading an Email message
Configuration and event processing
Address book maintenance
User management

All of these can be customized if required, although a number of fully working example
templates are provided.
