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".
