Странное поведение sendmail

При загрузке FreeBSD 7 вроде как запускаются несколько sendmail-ов:

Jul 18 15:52:01 d672 sm-mta[823]: starting daemon (8.14.3): SMTP+queueing@00:30:00

Jul 18 15:52:01 d672 sm-msp-queue[832]: starting daemon (8.14.3): queueing@00:30:00

...

Jul 18 15:52:51 d672 sm-mta[847]: daemon IPv4: problem creating SMTP socket

Jul 18 15:52:51 d672 sm-mta[847]: NOQUEUE: SYSERR(root): opendaemonsocket: daemon IPv4: server SMTP socket wedged: exiting

Вот содержимое rc.conf:

defaultrouter="xxx.xxx.xxx.xxx

hostname="my.domain.ru"

ifconfig_em0="inet xxx.xxx.xxx.xxx netmask 255.255.255.252"

keymap="ru.koi8-r"

font8x14="cp866-8x14"

font8x16="cp866b-8x16"

font8x8="cp866-8x8"

scrnmap="koi8-r2cp866"

sshd_enable="YES"

apache22_enable="YES"

proftpd_enable="YES"

named_enable="YES"

sendmail_enable="YES"

sendmail_submit_enable="NO"

dovecot_enable="YES"

mysql_enable="YES"

firewall_enable="YES"

firewall_type="/etc/firewall.conf"

enable_quotas="YES"

В итоге, однако, sendmail работает. Но непонятно, почему появляются такие сообщения и как от них избавится?

Спасибо!
