I have FreeBSD 6.0-RELEASE.
It seems there is collision between /etc/defaults/rc.conf and
/etc/rc.sendmail in sendmail startup control.
In /etc/defaults/rc.conf:
sendmail_enable=NO# Run the sendmail inbound daemon (YES/NO).
In /etc/rc.sendmail:
...
start_mta()
{
case ${sendmail_enable} in
[Nn][Oo][Nn][Ee])

So sendmail doesn't startup during system startup only if there is
sendmail_enable=NONE in /etc/rc.conf.
True.
Maybe I don't understand something?
Yes, you are missing something. The `sendmail_enable' variable is
overloaded for two different purposes, which do not necessarily conflict
with each other.
sendmail_enable=NO
This disables _only_ the ``inbound Sendmail daemon''.
sendmail_enable=NONE
This value disables _all_ Sendmail daemons.
The fine difference here is that in recent Sendmail versions, Sendmail
can run one or more daemons for:
- Receiving email messages from local programs. This is the
submission daemon, listening by default only to port 127.0.0.1:25.
The fine-grained tunable for this daemon is `sendmail_submit_enable'.
- Handing off locally submitted messages from the `submit' queue to
a mail relay server (`SMART_HOST' in Sendmail's language). This
is very useful when combined with `sendmail_submit_enable' if you
are not running a publicly visible mail server. You can use the
`submit' daemon as a queueing mechanism for locally sent email and
periodically flush its queue, sending all outgoing messages on
their way out with the Sendmail MSP queue runner.
The tunable for the MSP queue runner is `sendmail_msp_queue_enable'.

- On a publicly visible mail server (i.e. one that hosts email for
one or more domains that are visible on the wide Internet), you
will almost certainly need to use sendmail_enable=YES too, to
make sure a Sendmail daemon listens on all the non-localhost
interfaces.
- The fourth option, `sendmail_outbound_enable', is something you
will probably never need with Sendmail. Don't worry about it yet.
