S-nail error no such directory /usr/bin/sendmail / permission denied

Question

I am trying to get email notifications setup with smartmontools but the test email does not reach my address. s-nail is an optional dependency of smartmontools and is installed. From my understanding it should work out of the box without any configuration but it doesn't.
I attempted to send an email manually for troubleshooting purposes with this command:
sudo echo "This is the mail body" | mailx -s "This is the subject" -r sendersemail [email protected]
The mailx command produced an odd error:
/usr/bin/sendmail: No such file or directory
If I create /usr/bin/sendmail directory (and chmod it to 777) I get this error:
/usr/bin/sendmail: Permission denied
"/home/dom/dead.letter" 10/251
... message not sent.
I am lost. Does anyone have any idea what is going on here?

Answer 1

There is no config, it's all at defaults with only s-nail package installed. Or did you mean other non-snail config? Did you use the command as per my original post exactly and was it  an external email? Did you have s-nail installed/configured before now?
I also now tried adding a .rcmail config from snail wiki linked before.
# All the examples require v15-compat!
set v15-compat
# ArchLinux-specific locations of certificates.
# Since these are subject to the ArchLinux update mechanism,
# use only those, don't try to load OpenSSL builtin ones.
# And use the TLS specific set: see "man 8 update-ca-trust"
#set ssl-ca-dir=/etc/ssl/certs
set ssl-ca-file=/etc/ssl/certs/ca-certificates.crt
set ssl-no-default-ca
# Require secure transport via protocol version TLS v1.2, exclusively.
# (Change this only [best on a per-account base, as below]
# when the remote server doesn't support this protocol!)
set ssl-method=tls1.2
# Request strict transport security checks
set ssl-verify=strict
# Essential setting: choose allowed character sets
# (Have a look at the "CHARACTER SETS" manual section)
set sendcharsets=utf-8,iso-8859-1
# When sending messages, wait until the Mail-Transfer-Agent finishs.
# Only like this you'll be able to see errors reported through the exit
# status of the MTA (including the builtin SMTP one)!
set sendwait
# To save a copy of sent messages somewhere (this will end up in your home directory)
set record=sentmail.mbox
# This may be interesting to gain some speedup when sending mail
set mimetypes-load-control
# This is optional, but you should get the big picture
# by reading the manual before you leave that off
set from="Your Name <youremail@domain>"
Still the same error. No surprise since this config doesn't add any new info that is not present in the mailx command.
