NetBSD test.example.com 10.1 NetBSD 10.1 (GENERIC) #0: Mon Dec 16 13:08:11 UTC 2024  mkrepro@mkrepro.NetBSD.org:/usr/src/sys/arch/amd64/compile/GENERIC amd64

>Description:
The privilege separation accounts (_dhcpcd _httpd _mdnsd _nsd _pflogd _proxy _rtadvd _rwhod _sdpd _tcpdump _tests _timedc _tss _unbound) are currently not included /etc/mail/aliases.

How about redirecting those accounts to /dev/null?

>How-To-Repeat:
$ echo test | mail -s test _tcpdump
$ ls -l /var/mail/_tcpdump
-rw-------  1 _tcpdump  wheel  474 Jul  2 00:32 /var/mail/_tcpdump
$
