ls -al /usr/sbin/sendmail
lrwxrwxrwx 1 root root 26 Aug 19 08:02 /usr/sbin/sendmail ->
/etc/alternatives/sendmail*
ls -al /etc/alternatives/sendmail
lrwxrwxrwx 1 root root 24 Aug 19 08:02
/etc/alternatives/sendmail -> /usr/local/sbin/sendmail*
But that doesn't survive any system install that overwrites /usr/sbin/sendmail
-- incl for example lsb, google-chrome, etc
OTOH a friend gave me this 'cheat'

sendmail-dummy-1.0-1.noarch
Which afaict
(1) 'properly' installs a pkg that provides a /usr/sbin/sendmail
(2) allows me to uninstall unnecessary mtas
(3) point at & use 'my' postfix install
(4) survives any sendmail-dependent pkg installs
(5) Doesn't require 'alternatives'
(6) frees me from distro-dependence, and keeps me on postfix upstream, using a
simple local config/install
Testing now. So far submit/send works as expected, using 'my' postfix. And no
more perms errors in my logs - yet.
