Try qmail's pop3d. It only works with Maildirs, but exim can write to a
Maildir. It's small and fast, and because of the Maildir structure (one
file per message), very good about disk IO. No files to copy around. And
Maildirs work reliably over NFS too. The best part about qmail-pop3d is
that its auth it separate from the actual POP server. It is launched in
a chain somewhat like this:
qmail-popup checkpassword qmail-pop3d
where qmail-popup asks for a username and password, passes those
to checkpassword (the default checkpassword by DJB auths from
/etc/passwd, but you can write your own to auth from anywhere, eg.
RADIUS, another file, MySQL) and if the auth is successful, runs
the qmail-pop3d (or you can even run a shell script which could
capture the IP address for POP-before-SMTP, and then exec the
qmail-pop3d). Very flexible, and very easy to use and understand.
If you need to modify its source code for any reason, it's also
very cleanly written and easy to understand.
