I have a fresh install of FreeBSD-RELEASE 14.0 done by my service
provider, which I upgraded to FreeBSD-RELEASE 14.1 yesterday (with help
from people here, in fact).

%uname -a
FreeBSD my.host.name 14.1-RELEASE-p5 FreeBSD 14.1-RELEASE-p5 GENERIC amd64

I'm reviewing sendmail configuration and I came to check whether my
sendmail had its setuid bit set. I discovered it does not. But then I
thought I'd find it had the setgid bit set. It also does not.

%ls -l $(which sendmail)
lrwxr-xr-x 1 root wheel 11 Nov 10 2023 /usr/sbin/sendmail -> mailwrapper

%ls -l $(which mailwrapper)
-r-xr-xr-x 1 root wheel 8648 Nov 4 22:34 /usr/sbin/mailwrapper

So I guess the FreeBSD designers compiled sendmail with a default group,
which must be ``mail'', which is the group in /var/mail, so that must be
how sendmail is able to deliver messages to local users.

I expected to find the program mail.local---for local mail delivery. I
do not find this program on root's path, but I find its manual page in
section 8. Should I not have this program? Where is it?

I'm reading the book

sendmail
Bryan Costales, George Jansen,
and Claus Afsmann with Gregory Neil Shapiro
O'Reilly, fourth edition, 2008, ISBN 978-0-596-51029-9

and they talk about mail.local as the program that delivers local mail.

You might find procmail (in /usr/local/bin/ after install) superior for
local mail delivery. It lets each user have their own filters for their incoming mail.

I always hear of procmail. It's now time to try it out. Thanks.
