For your own installation? Sure, do as you please (though I encourage
you to read below).
As a default? I don't recommend it, for POLA, if nothing else (at
least, it would be POLA for those of us who have been using UNIX &
sendmail for... well, a while...).
That said, even the admittedly primitive MUA called "mail" allows an
individual invoker to override the system default "MeToo" setting --
from "man mail":
metoo Usually, when a group is expanded that contains the sender, the
sender is removed from the expansion. Setting this option causes
the sender to be included in the group.
If other MUAs fail to implement the feature, and it's wanted, either
change the MUAs in question or switch to MUAs that more nearly meet your
needs. Or go ahead and switch your installation default, but you might
want to let your anyone who might be using the machines in question
know ahead of time. (You may note that I'm looking at this from a
perspective that assumes that such changes may well affect a number of
people, typically >>1.)
And please note that sendmail provides a way to turn the "metoo" feature
*on* via the command line, but does not (as far as I know) provide a way
to turn it *off* via the command line.
Another reason for not changing it (which may well be a borderline
religious issue, but life's like that sometimes) is that changing the
sendmail.cf isn't something I'll recommend, period. I would recommend
changing the .mc file & re-generating the sendmail.cf, if there's a
reasonable change that's wanted in the sendmail.cf. There's a way to
accomplish the stated objective via the .mc files; it's documented iin
the 2nd ed. Bat book. (BTW, that documentation also mentions some
additional reasons to leave the option turned off by default.)
Cheers,
david
