I'm sorry to give a flaky answer, but whatever pop server is installed
with qmailrocks.  Courier does imap in this setup, I think it also
does pop.  I did a manual login to the pop server
(#telnet localhost 110)
and was able to successfully log into my account and list my mail.  I
assume that means that the pop server is working properly?
