qpopper has a continuing, very doubtful history regarding security/bug
issues. Each new release comes with a major bug (often a new buffer
overflow). You better avoid that application. Too because it is not
provided by CentOS. Use dovecot - quick, easy to configure and shipping
with CentOS base.
Comment on your question about the MTA and MSA services by Sendmail: if
you explicitly set DAEMON_OPTIONS for the MSA or TLSMTA you too have to
explicitly set them for the MTA - else the MTA is disabled.
You can easily play around with it: selective activate and deactivate
DAEMON_OPTIONS for the services in sendmail.mc, rebuild the sendmail.cf
from it (make -C /etc/mail) and then look at the results by running
"grep DaemonPortOptions /etc/mail/sendmail.cf".

Advice taken.. I did some extensive searching of the archived discussions, and did not find any one thing that related to setup of dovecot, nor could I find any kind of document describing setup of sendmail/cyrus-imapd. Even google did not return what I'd consider fair game unless I were installing from sources, which I'm not. That said, is there a document that describes setup of dovecot? All I really need is pop, as there is only one or two mail accounts on the machine.
