#262139 — SMART error messages being sent to the wrong address

I'm running Debian/Bookworm on a headless server. The box has had a 
variety of roles and names. At one time it was called fanny after the 
groundbreaking rock band and because it had a lot of fans in it. This 
latter attribute led to it being made into a file server and renamed 
BigData.

The problem I'm having is that SMART error messages are being sent to 
root@fanny.<my domain> instead of to me. /etc/aliases has all mail to 
root going to me, but because this addressed to root on a machine with a 
different name, it goes out and I only get the message when it bounces 
(because the machine name no longer exists).

I can't find where the e-mail address is being set. Tracing down the 
smartmontools config files didn't turn up any obvious problems.

Can anyone point in the right direction?

Thanks

Add a CNAME record to your DNS.

Mail delivery is supposed to ignore CNAME records.  Perhaps you meant
to say an MX record.  But either way, the OP's question is still not
answered -- where is the recipient address configured?

My guess would be "in the system's MTA".  I'm guessing the SMART tools
are simply sending to "root" with no domain, and relying on the system's
MTA to fill in the recipient domain.  I'm guessing this MTA is not
configured properly.

The OP should verify this by running something like:

    echo test | mailx -s test root

And see how the message headers get written, and where the message goes.
If it turns out my guesses are right and the MTA is misconfigured, then
we'll know the next steps.

If it turns out my guesses are wrong, and the MTA is fine, then we'll
have to figure out how these SMART tools are configured.

Other mail from that server is being sent properly. It's just the SMART 
messages that are going to the wrong place.

smartd.conf can have a -M exec option to call another script instead of
simple mail. Do you have one?
smartd can get some options from /etc/default/smartmontools
and /etc/smartmontools can hold scripts called for sending mail.
(perhaps /etc/smartmontools/run.d/10mail)
check all this

The email address is set with the -m option in the file
/etc/smartd.conf. I'd check that to see if you changed it from the
default ('root'). And you should be able to set it to what you want.

Does anybody read signatures any more?

No. The -m option is "root".

If Greg and Charles' suggestions do not work, I would grep for it.

    $ sudo su -
    $ grep -iIR fanny /etc

That should uncover places the old name shows up.

If you are sudoing just for one command, even better:

  sudo grep ...

will do. Besides saving quite a few keystrokes, it has other upsides.

Or sudo bash - or whatever your preferred shell is.

Thanks Jeff. It looks like it came from /etc/mailname.
