This command aims at replacing the builtin `sendmail` command which
gives too much privileges to the caller. For example, Postfix's
sendmail(1) command can list the mail queue (`-bp`), rehash the alias
database (`-bi`), start a daemon (`-bl`, `-bd`), or flush the queue
(`-q`); all remnants of the old Sendmail binary, which probably is
Turing-complete on its own.
.
Instead, rsendmail can easily queue mails on a system without giving
any extra privileges to the client. In turn, this makes configuring a
satellite system like a laptop or a workstation as simple as adding
an SSH key to an `authorized_keys` file. That key can then send
email, but *only* send email: no shell access or server management.
.
This can of course be accomplished by a regular SMTP client, but that
requires passwords, and passwords are weak.
