[exim] POP3 Server with exim

Hi All,



I am looking for a good pop3 server. The catch is that I need the pop3
server to do authentication for a file or some other means of authentication
except sql based. I am setting up a mail server that runs on minimal
hardware and a sql server is using to much ram. Any other ideas if not this
is not possible? Maybe a good and easy POP3 server that I can modify for
this kind of authentication?



Thanks,

Michael
