You could have downloaded Finder Mail 0.5 for Mac from our application library for free. The software lies within Communication Tools, more precisely E-mail.
From the developer:
The aim of Finder Mail is to provide a clean, perfect and efficient interface for POP3 mailboxes. Rather than packing all the functionality of a mail client into one large application, Finder Mail splits common components into small individual applications. These are quick to load and dont interfere with the each other. Furthermore, Finder Mail uses your Mac's standard Finder interface to file all your emails.
