Hi, we have the sendmail.service enabled by default
even in the minimal installation.
I only use Thunderbird as my email client.
May I uninstall sendmail? Is it needed for something
I'm not aware of?

Logwatch and other periodic email messages from the system
to the root
user (or his designee) will get lost. I embraced this folly
years ago
and had to reinstall SOME mail program. I suppose PostFix
would do as
well as SendMail.

Oh yes, that's what I had in the back of my mind when I asked the question.
So back to enable it again.
"Just for the record, I used to do this after every Fedora installation:
yum install postfixyum remove sendmail
chkconfig postfix onservice postfix start
(well, I still do this -- just did for F17 -- but now 'chkconfig' and 'service' should be replaced by their systemd counterparts)
Works like a charm, as jdow posted, postfix is configured to replace sendmail completely.

Hi André.
But what difference would it make to replace sendmail for postfix?
Is sendmail some security breach and postfix isn't, or something like that?
Postfix is arguably more configurable. It is possibly more secure. But
that only matters if you are running your own MTA on the web. That's not
generally a recommended practice. (You run afoul of various black lists
for "dialup" or "dynamic" addresses.) As long as you're just using it
to transfer internal mail and the ports are closed to the outside world
pick the one with the smaller footprint. Or use something else designed
for this purpose with a very small footprint. (I'm just a tad too lazy to
try to find, install, and get such a tool working or I would.)
