As a postscript, I'm not at all convinced that there's a significant
difference in performance between pop-before-smtp and DRAC --- or,
if there is, which one wins. File::Tail is _slick_. Eyeballing a
strace of my pop-before-smtp in fairly active processing, I really
think it's probably doing less work all up than DRAC would to do the
same job.

For my money the big differences are:

(1) DRAC works better with server farms, where multiple machines may
    be offering pop/imap service and/or smtp service, while

(2) pop-before-smtp is only good on single-server boxes, but is
    simpler to install (no patches to pop/imap daemons required) and
    doesn't require RPC.

As you say, you don't have to open up portmapper --- but even if you
had to open it, you'd only have to open it to machine[s] where you
are running pop/imapds. If you're able to use pop-before-smtp, then
you probably don't need to open up portmapper to anything off the
server, so DRAC really isn't that much awfuller.
