The error shown came from sendmail --- it would be highly irregular
for apache to attempt to write (let alone be able to write) into
/var/spool/mqueue. That directory should be writable only by root.

That's for the new sendmail MSP (mail submission process). It's the
sm-msp process that your web-mail scripts are interacting with if they
put new messages onto the queue by piping them into
/usr/sbin/sendmail. The MSP process then passes them off to the
sm-mta (Mail Transport Agent) using ESMTP, generally to the sendmail
process listening on localhost port 587/tcp. This separation of
functions allows the SUID bit on the sendmail binary to be dropped.

=46rom /usr/src/UPDATING:
20020411:
New sendmail startup scripts have been installed to make it
easier to use alternative MTAs with FreeBSD. The rc.conf
variable mta_start_script can be set to a script for starting
an alternative MTA or to "" to prevent any MTA from being
started at boot.
20020404:
The sendmail startup code in /etc/rc has been changed to deal
with a non-set-user-ID sendmail binary. Setting the rc.conf
variable sendmail_enable to "NO" no longer prevents any sendmail
daemons from starting. Instead, set sendmail_enable to "NONE"
to prevent any MTA from being started at boot.
20020404:
Due to the import of sendmail 8.12.2 (see 20020325 entry), a new
user and group are required in order for sendmail to run as a
set-group-ID binary. A 'make installworld' will use the new user
and group to set the owner and group of /var/spool/clientmqueue
and will fail if the new user and group do not exist. The 'smmsp'
user and group must be merged from src/etc/group and
src/etc/master.passwd before using 'make installworld'.
'mergemaster -p' will do this. You may need to install
mergemaster before this will work if you are updating from a
very old version of stable. This can be done with:
cd /usr/src/usr.sbin/mergemaster; make all install
20020325:
sendmail 8.12.2 has been imported. The sendmail binary is no
longer a set-user-ID root binary and the infrastructure to support
command line mail submission has changed. Be sure to run
mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf,
and /etc/mail) and read /etc/mail/README for more details.
This all occurred between 4.5-RELEASE (on 20020129) and 4.6-RELEASE
(on 20020615). The sendmail version in 4.7-STABLE last time I did a
buildworld (about 5 days ago) was:
% telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 smtp.infracaninophile.co.uk ESMTP Sendmail 8.12.6/8.12.6; Tue, 21 J=
an 2003 13:54:59 GMT
quit
That's the same version as in 4.7-RELEASE according to cvs-web. The
version in 4.5-RELEASE was sendmail-8.11.6 ---
