tl;dr -- netstat with a couple options i & d.
I'd never really noticed it; it probably would be helpful to put the
output just to make sure things are lining up, and rather than just hand
you what I think is going on, this seems like a good time to teach
people what little I know of fishing.
if the email you're seeing is part of a daily run, it's set by the
system and not something you put in as root user (you can do crontab -l
as root to verify it's not there), then there's the system cron file in
# Perform daily/weekly/monthly maintenance.
1 3 * * * root periodic daily
15 4 * * 6 root periodic weekly
30 5 1 * * root periodic monthly
that seems like a pretty good suspect, man on 'periodic' -
If an argument is an absolute directory name it is used as is,
it is searched for under /etc/periodic and any other directories speci-
fied by the local_periodic setting in periodic.conf(5) (see below).
check the directories
root at nexus:/etc/periodic/daily # ls
100.clean-disks 330.news 440.status-mailq
110.clean-tmps 400.status-disks 450.status-security
120.clean-preserve 401.status-graid 460.status-mail-rejects
130.clean-msgs 404.status-zfs 480.leapfile-ntpd
140.clean-rwho 406.status-gmirror 480.status-ntpd
150.clean-hoststat 407.status-graid3 500.queuerun
200.backup-passwd 408.status-gstripe 510.status-world-kernel
210.backup-aliases 409.status-gconcat 800.scrub-zfs
300.calendar 420.status-network 999.local
that 420.status-network seems like a good candidate
root at nexus:/etc/periodic/daily # sh -x 420.status-network
+ echo 'Network interface status:'
Network interface status:
+ netstat -i -d

and I think you'd find that's a decent match for what you get in your email.
