# ifconfig lo0
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
         inet6 fe80::1%lo0 prefixlen 64 scopeid 0x3
         inet6 ::1 prefixlen 128

(lo0 looks unconfigured to me)

# sockstat | grep :25
root     sendmail   7371  3  tcp4   *:25                  *:*
root     sendmail   7371  5  tcp6   *:25                  *:*

(that looks fine to me)

# ls -la /usr/libexec/sendmail/
total 676
drwxr-xr-x  2 root  wheel     512 Mar 30 21:03 .
drwxr-xr-x  5 root  wheel    1536 Mar 30 21:03 ..
-r-xr-sr-x  1 root  smmsp  669788 Mar 30 21:03 sendmail

(looks OK to me, too)

# mount | grep /usr
/dev/aacd0s1f on /usr (ufs, local, soft-updates)

(Looks normal to me, too)

Thanks
