I think it has mailx installed by default

mailx is the client, not the mailer. But most people actually want to use this and don't realize it and so don't ask what they mean. So chances are, he wants to use mailx but technically he is set to send emails without it.

Just want to email out a log file.

From what application?

Alex Sage

@scottalanmiller bash script, via command line is fine.

If you want to do it from BASH, you need to add a command to send. mailx is the one to use.

dnf install mailx

Null message body; hope that's ok
/usr/sbin/sendmail: No such file or directory
"/root/dead.letter" 9/243
. . . message not sent.

Is there really no MTA by default? Is this one of Jared's minimal installs instead of server? That might do it.

dnf install postfix
systemctl start postfix
systemctl enable postfix

@scottalanmiller postfix installed, running and enabled.

The command just hangs:

mail -s "Test" [email protected]

It's not hung, it's waiting for the body of the email. Try this...

mail -s "Test" [email protected] < /etc/passwd

Bingo, Gmail thinks it's spam, but that makes since

Alex Sage

@scottalanmiller so do I even need postfix?

Yes, mailx is only a client, it's telling Postfix to send it. if you wanted to send through Postfix by hand, you could.

Fun = telnet to postfix and send E-mail that way

Right, it's a standard thing to have to learn to do, but once you learn how, you never want to do it again. But it's standard for students to have to do it to learn how network protocols work and it is a great demonstration of "you don't need a client."

It is also demonstrates a reason to appreciate having a decent client app.
