It's a Perl POP3 to Web gateway. That is, it can read mail from a POP3 mail server and display it using HTML on a web server. It can even display MIME attachments, which is incredibly sexy.
Our Review: acmemail is a webmail application, allowing you to set up an interface to a POP3 server via an HTML browser. Attachments are supported - it will display graphics files inline, and provide links to download other attachments. Fully featured, and with a good interface, its only downfall is the fair bit of time required to set it up.
