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?
Regards.

Just go to services and shut it off

It was already mentioned that sendmail is MTA (may it be called a mail
server for simplicity). I really don't know why a regular desktop user
is forced to have such infrastructure installed and operational out of
the box only to allow some poorly designed programs to pass messages to
the user. I think it's one of that old UNIX approaches that need to be
revised and changed to better suite desktop Linux users.
I think you can disable sendmail service (it is not installed by default
in Debian) but removing package might break some other package
dependencies so don't do it.

What? One that works well, needs replacing with something new, to bring
about a new set of problems?
Only because something works well, doesn't mean it
is the best choice
for everyone and forever. It always could have been better.
What alternative do you think would be better to pass log messages
onto
the user(s)? It has to be something that works when the user isn't
currently logged on, as well as when they're on. Keeps the messages
until the user goes to look for them.
I can not responsibly propose any alternative
right now and it seems it
is not the topic of this e-mail. I assure you there are already better
alternatives for desktop and minimal installations to exchange
diagnostic messages than having a full blown mail server installed.
Simplicity is divine.
Using email is quite convenient for all those purposes, and makes it
very easy to forward messages onto someone else, should you need a
second set of eyes to check something out.
How often a regular desktop or mobile Linux user checks that e-mails
thrown in root's mailbox somewhere in the system? I read logs regularly
on my servers, sometimes on my desktops but I hardly ever read root's
mailbox on my desktop and I don't think I'm alone. I do not even bother
to configure my GUI mail client to do this.
I really have nothing against passing diagnostic messages over mail
infrastructure but I don't think it is the best approach for all Linux
users today. It should be more like an option to choose not enforcement.

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 postfix
yum remove sendmail
chkconfig postfix on
service 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.

Andre

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.

Well, yeah: that's what alternatives does. If you switch it to another
MTA the "outer" (generic name -> /etc/alternatives) links stay the
same but the redirects within /etc/alternatives (pointing to the real
target) are updated to reflect the chosen option.
Same thing for java, ld and the other alternatives link groups used on
Fedora.
So it's not a problem. All that happens is the mta link is
redirected to which ever MTA is active.
Nobody suggested it was. Sergio asked about removing sendmail and
since this is handled in Fedora using alternatives and virtual
provides for MTAs and smtp daemons those topics are relevant to the
thread.
So the potential problem has been covered and dealt with.
You've lost me I'm afraid. The thread was about removing sendmail: I
don't know what problem you are referring to.

Umm, where, Jdow? I see five replies to the thread (not including this
one) but nobody mentioned alternatives or the virtual provides for
smtpdaemon/MTA which is kinda important in understanding how the
packaging of these components work on Fedora systems.
You can also use one of the simple smtp command packages (ssmtp,
esmtp) if you prefer not to have a receive-capable MTA installed on
the system. These provide /usr/sbin/sendmail and can be selected in
alternatives but do not provide smtpdaemon and cannot listen on the
network for incoming mail. They are a good choice for personal systems
or systems where you'd rather not administer a full-blown MTA.
For some reason the current ssmtp package doesn't list the
/usr/sbin/sendmail provide but it is included in the package. I
haven't checked to see if that would cause any problems while
attempting to remove any smtpdaemon.
It's been covered as a problem in that it is not a problem - at least
on the RHEL trees. SL2 has this sequence of links:
$ ll /usr/sbin/sendmail
lrwxrwxrwx. 1 root root 21 Jun 7 2011 /usr/sbin/sendmail -> /etc/alternatives/mta
$ ll /etc/alternatives/mta
lrwxrwxrwx. 1 root root 27 Jun 7 2011 /etc/alternatives/mta ->
/usr/sbin/sendmail.sendmail
So it's not a problem. All that happens is the mta link is redirected to
which ever MTA is active.
So the potential problem has been covered and dealt with.

Sendmail is a MTA "Mail Transport Agent" Thunderbird is a mail client.
Thunderbird talks to an MTA. If you are running a mail sever on this
machine you will need an MTA, Sendmail is as good as any.
You should consider running Dovecot "IMAP server" with Sendmail if you
are sending and receiving email through this machine.

I think things should depend on "MTA" or "smtpdaemon" rather than
sendmail itself. The MTA on Fedora systems is hooked into the
alternatives infrastructure so even if you install and enable postfix
or another MTA there is a /usr/sbin/sendmail pointing to an
appropriate binary that can be called in sendmail's place.
