Maybe I wasn't clear enough: You explicitly enabled the MSA with
authentication enforced and TLSMTA (SMTPS), so the MTA is disabled if
not explicitly instructed to run by a dedicated DAEMON_OPTIONS line. No,
that didn't change for a long time. To avoid a listener on an IPv6
enabled interface is a different matter. A the sendmail.mc in its
commented way shows, you can selective say whether to have an IPv4 MTA
listener or IPv6 one, or both. Btw. the default sendmail.mc shipping
with FreeBSD has those commented IP version splitted DAEMON_OPTIONS

More is explained in cf/README.
