* https://packages.debian.org/fr/stretch/heirloom-mailx : This dummy package is provided to provide a smooth upgrade path from heirloom-mailx to s-nail. It only contains symlinks to the s-nail binary and manpage. 

heirloom-mailx, dans sa version pour stretch, est différent des versions précédentes et n'est plus qu'une coquille vide. 
Le paquet réellement installé est s-nail.
Et effectivement la commande <code>s-nail</code> est bien disponible.

<code>man s-nail</code>
S-nail is thus the user side of the Unix mail system, whereas the system side (mail-transfer-agent, MTA) was traditionally taken by sendmail(8); today postfix(1) or exim(8) are often used for this purpose instead.  If the [Option]al SMTP feature has been built into S-nail then the system side is not a mandatory precondition for mail delivery.

Cela semble signifier qu'un MTA doit être présent pour que s-nail fonctionne.

<pre>
$ echo tpi | s-nail toto@dom.tld
Cannot start "/usr/sbin/sendmail": executable not found (adjust *sendmail* variable)
</pre>

==s-nail==

La commande est dispo pour les utilisateurs.
(Contrairement à postfix où, par défaut, seul root a accès).

<code># s-nail -s test0948 -a mansnail.txt xxx@yyy.tld</code>

Mais faut ctrl-d pour expédier

<code># echo bla | s-nail -s test0959 xxx@yyy.tld</code> envoit bla
